Paris-headquartered EU sovereign cloud. Re-verified 2026-08-22 against the live TEM page: Essential (pay-as-you-go) now includes only 300 emails at $0.291/1k — the former 10,000/mo free tier is gone from their published plans. Scale ($93.28/mo) bundles 100k emails, a managed dedicated IP and 99.9% SLA — the IP ships WITH the plan, not as an add-on (dedicatedIpMonthlyCost stays null).

MailerSend
MailerSend (mailercloud family)$10.90 /month
$1.09/1kTransactional-only quote 500 Free/mo
Captured 2026-08-22 from mailersend.com/pricing, 'Pay monthly' + USD (the page defaults to yearly −10%: Hobby $6.30, Starter $31.50, Professional $99 — monthly rates are $7/$35/$110). Hobby includes 5k emails then $1.50/1k; Starter includes 50k then $1.30/1k; Professional ($110) carries the same 50k included volume but adds account manager/deliverability consultation — dominated on price by Starter, so bands above model Hobby→Starter. Volume slider scales included volume beyond these floors; dedicated IP is an Enterprise-only add-on (>100k/wk), rate not published self-serve.

Learn about Scaleway →5. Head-to-Head Provider Comparisons
Postmark vs SendGrid Postmark is the gold standard for transactional email speed, deliverability transparency, and 45-day message history. SendGrid (Twilio) is cheaper at high volume and includes a built-in marketing campaigns suite. Compare Specs & Pricing →Resend vs Postmark Resend offers the best modern developer experience with native React Email components, webhooks, and modern SDKs. Postmark offers deeper delivery tracking, longer analytics retention (45 days vs 30 days), and dedicated transactional infrastructure. Compare Specs & Pricing →Brevo vs Mailgun Brevo provides complete EU GDPR data residency, 9,000 free emails/month (300/day), and an all-in-one marketing CRM. Mailgun (Sinch) provides developer-focused routing, inbound parse APIs, and enterprise delivery scaling. Compare Specs & Pricing →SendGrid vs Amazon SES Amazon SES is dramatically cheaper ($0.10/1k emails, up to 70-80% savings) but requires self-managed IP warm-up and raw AWS plumbing. SendGrid provides a turnkey platform with analytics, templates, and managed deliverability. Compare Specs & Pricing →Resend vs SendGrid Resend is the modern developer-favorite alternative to SendGrid, eliminating legacy UI clutter and introducing code-first React Email templates. SendGrid remains the higher-throughput enterprise choice with marketing campaign automation. Compare Specs & Pricing →Scaleway vs Brevo Both offer 100% European data sovereignty shielded from the US CLOUD Act. Scaleway is a developer utility priced at just $0.291/1k pay-as-you-go (300 emails included). Brevo is a full-featured marketing + transactional platform with visual drag-and-drop builders. Compare Specs & Pricing →Mailjet vs Scaleway Transactional Email Both are EU-sovereign picks, but they solve different jobs: Mailjet (French HQ, EU processing) bundles a marketing/newsletter suite on top of transactional sending from $17.49/mo, while Scaleway is a raw transactional-only API at $0.291/1k ($0.233 high-volume) with Paris residency. Pick Mailjet if you also send campaigns; pick Scaleway for pure API email at the lowest sovereign cost. Compare Specs & Pricing →Postmark vs Brevo Postmark is the transactional specialist: stricter stream separation, 45-day message history, and proven inbox placement — at premium per-1k rates ($1.25/1k base). Brevo bundles EU-sovereign transactional sending (from $0.45/1k usage-based) with a full marketing CRM and 9,000 free emails/month. Pick Postmark for pure transactional reliability; pick Brevo if you also run campaigns or need EU data residency. Compare Specs & Pricing →Postmark vs Mailgun Both are developer-grade platforms, but they optimize different jobs: Postmark for best-in-class transactional delivery transparency (45-day logs, strict stream separation), Mailgun for API breadth — inbound parsing, email validation, and marketing sends from one account. Postmark starts cheaper ($15/mo incl 10k vs Mailgun’s $35 Foundation incl 50k); Mailgun wins on feature surface and high-volume rates. Compare Specs & Pricing →Postmark vs Amazon SES The managed-specialist vs raw-infrastructure trade-off in its purest form: Postmark charges $1.25/1k base (stepping to $0.35/1k past 1M) for turnkey deliverability, templates, and 45-day history, while Amazon SES bills a flat $0.10/1k with no standing free allowance — if you bring your own warm-up, monitoring, and bounce plumbing. Compare Specs & Pricing →Postmark vs Scaleway Transactional Email Scaleway is the budget sovereign pick: $0.291/1k ($0.233 on the $93.28/mo Scale plan past 100k) with Paris residency and no monthly minimum. Postmark costs more ($15/mo incl 10k, $1.25/1k base) but buys elite deliverability tooling, 45-day history, and inbound parsing. Choose Scaleway for cost-sensitive or EU-bound sending; choose Postmark when deliverability failures cost more than the bill. Compare Specs & Pricing →Postmark vs Mailjet Mailjet bundles EU-hosted transactional sending ($17.49/mo Essential incl 15k) with a newsletter/campaign suite and a drag-and-drop builder; Postmark stays transactional-purist with superior delivery transparency and 45-day logs. If campaigns matter, Mailjet; if inbox placement for receipts/password-resets matters most, Postmark. Compare Specs & Pricing →Postmark vs Mailchimp Transactional (Mandrill) Mandrill sells prepaid 25k-email blocks ($20/block, dropping to $10 at 161+ blocks — $0.80 down to $0.40/1k) and slots into the Mailchimp ecosystem; Postmark sells simplicity and trust at $1.25/1k base with 45-day history. Mandrill wins big-volume economics; Postmark wins hands-off deliverability and cleaner ops. Note Mandrill bills whole blocks — unused block credit expires monthly. Compare Specs & Pricing →Postmark vs MailerSend MailerSend undercuts Postmark on entry cost ($7/mo Hobby incl 5k vs $15/mo incl 10k, then $1.50/1k vs $1.25/1k overage) and adds a friendlier all-in-one dashboard; Postmark counters with 45-day history, deeper deliverability pedigree, and a self-serve dedicated IP (MailerSend reserves IPs for Enterprise). Pick MailerSend for budget + UX; Postmark for mission-critical transactional trust. Compare Specs & Pricing →Postmark vs SMTP2GO SMTP2GO competes on flexible global SMTP relay and a generous free tier (1,000/mo vs Postmark’s 100 lifetime test sends), with Professional ($75/mo incl 100k) including a dedicated IP. Postmark remains the deliverability-and-transparency benchmark (45-day logs, inbound parsing) but at higher per-1k. SMTP2GO for pragmatic volume sending; Postmark for zero-compromise transactional operations. Compare Specs & Pricing →Brevo vs SendGrid Both are combined transactional+marketing platforms. Brevo leads with EU data residency, a 9,000-email free tier, and contact-based marketing plans; SendGrid (Twilio) leads with higher throughput ceilings, granular sub-user architecture, and Twilio-channel integration. Transactional rates converge (~$0.25–0.45/1k); the decision usually hinges on geography and whether your marketing lives in the same tool. Compare Specs & Pricing →Mailgun vs SendGrid The two legacy heavyweights overlap heavily; the differences are emphasis. Mailgun leans into developer primitives — inbound parsing, validation API, precise tag analytics — starting at $35/mo incl 50k. SendGrid leans into scale and ecosystem: $19.95/mo incl 50k entry, Twilio channel bundling, and bigger enterprise throughput. Below 50k they are close; above, SendGrid’s $89.95 tier undercuts Mailgun’s $80 Growth only on included volume math — compare against your real mix. Compare Specs & Pricing →Mailgun vs Resend Resend is the modern code-first challenger: clean APIs, native React Email, 3,000 free emails/month, $20/mo Pro incl 50k. Mailgun is the established platform with inbound parsing, validation APIs, and heavier enterprise machinery from $35/mo. Developers shipping product email start with Resend; teams needing inbound + validation suites or deep log control land on Mailgun. Compare Specs & Pricing →Amazon SES vs Mailgun SES is raw infrastructure at $0.10/1k flat with nothing managed; Mailgun is a managed layer ($35/mo incl 50k, then $0.35/1k) selling inbound parsing, validation, analytics, and support on top. If your team can absorb bounce handling, warm-up, and reputation monitoring, SES’s margin advantage is enormous; if email is critical-but-not-core, Mailgun’s tooling pays for itself. Compare Specs & Pricing →Scaleway Transactional Email vs Mailgun Scaleway is the minimal sovereign utility: $0.291/1k pay-as-you-go (300 included), Paris residency, no plan fees until the $93.28/mo Scale tier. Mailgun is a full platform — inbound parsing, validation API, marketing streams — from $35/mo incl 50k. If you only need outbound transactional email and value EU jurisdiction, Scaleway is dramatically cheaper; if you need the surrounding tooling, Mailgun justifies its floor. Compare Specs & Pricing →Mailjet vs Mailgun Two veterans with different centers of gravity: Mailjet (French HQ, EU processing) bundles newsletter campaigns and a drag-and-drop builder with transactional sending from $17.49/mo incl 15k; Mailgun (Sinch) goes deeper on developer APIs — inbound parse, validation, granular webhooks — from $35/mo incl 50k. EU marketing-inclusive stacks pick Mailjet; API-heavy product teams pick Mailgun. Compare Specs & Pricing →Mailgun vs Mailchimp Transactional (Mandrill) Mandrill prices in prepaid 25k blocks ($20 down to $10 — $0.80 to $0.40/1k) inside the Mailchimp account model; Mailgun uses monthly plans ($35 incl 50k, $0.35/1k overage stepping to $0.15). Mandrill wins above ~1M/month where its block discounts bite; Mailgun wins below that with inbound parsing, validation APIs, and no whole-block waste. Compare Specs & Pricing →MailerSend vs Mailgun MailerSend targets small-to-mid teams wanting a friendly all-in-one dashboard at low cost ($7/mo incl 5k, $35/mo incl 50k); Mailgun targets API-centric teams needing inbound parsing, validation, and scale machinery ($35/mo incl 50k, deeper high-volume tiers). At equal 50k volume they cost the same on paper — the split is UX/simplicity versus platform depth. Compare Specs & Pricing →SMTP2GO vs Mailgun SMTP2GO keeps it simple: global SMTP relay, free 1,000 emails/month, $15/mo Starter incl 10k, Professional $75/mo incl 100k with dedicated IP included. Mailgun adds developer depth (inbound parse, validation API, marketing streams) from $35/mo incl 50k. Pure outbound relay at modest volume favors SMTP2GO; platform features favor Mailgun. Compare Specs & Pricing →Amazon SES vs Resend Resend wraps modern DX around exactly the problem SES leaves to you: Resend gives React Email templates, clean SDKs, and a real dashboard at $20/mo incl 50k then $0.40/1k; SES gives raw $0.10/1k infrastructure with sandbox gating and self-managed deliverability. Startups optimizing velocity pick Resend; cost-optimizing platforms with ops muscle pick SES. Compare Specs & Pricing →Resend vs Scaleway Transactional Email Both skew developer-simple, but they optimize different constraints: Resend for experience (React Email, best-in-class console, 3,000 free sends) and Scaleway for cost-plus-sovereignty ($0.291/1k pay-as-you-go, Paris residency). US-focused teams pick by taste; EU-jurisdiction requirements tip it to Scaleway. Compare Specs & Pricing →Mailjet vs Resend Mailjet is the EU bundle play — transactional plus newsletter campaigns, contact segmentation, French data processing — from $17.49/mo incl 15k. Resend is the developer-experience play — React Email, modern APIs, generous free tier — at $20/mo incl 50k. If campaigns live elsewhere, Resend is cleaner; if you want one EU-hosted tool for both streams, Mailjet. Compare Specs & Pricing →Resend vs Mailchimp Transactional (Mandrill) Two different philosophies of transactional email: Resend sells modern developer ergonomics at $20/mo incl 50k then $0.40/1k; Mandrill sells prepaid Mailchimp-integrated blocks from $20/25k ($0.80/1k, falling to $0.40/1k at 4M+). At low volume Resend includes more and bills cleaner; at multi-million volume Mandrill’s block discounts win — if you accept whole-block ceil billing and the Mailchimp orbit. Compare Specs & Pricing →MailerSend vs Resend The friendliest matchup in the field — both pitch approachable dashboards and fair entry pricing. MailerSend starts cheaper ($7/mo Hobby incl 5k) with stronger built-in deliverability tooling (suppression lists, split testing); Resend answers with React Email authoring, a bigger free tier (3,000 vs 500), and higher included volume at Pro ($20 incl 50k vs $35). Pick by authoring workflow and free-tier appetite. Compare Specs & Pricing →Resend vs SMTP2GO SMTP2GO is pragmatic relay: anycast SMTP + API, 1,000 free emails/month, $15/mo incl 10k, Professional bundling a dedicated IP at $75/mo. Resend is developer-first: React Email, modern SDKs, 3,000 free sends, $20/mo incl 50k. Volume-for-volume Resend usually costs less until SMTP2GO’s Professional tier; feature-wise it depends whether you want authoring ergonomics (Resend) or relay flexibility + included IP (SMTP2GO). Compare Specs & Pricing →Brevo vs Resend Resend is the developer-purist pick: React Email, modern SDKs, 3,000 free sends, $20/mo incl 50k — transactional only. Brevo is the all-in-one EU platform: CRM, campaigns, automation, 9,000 free emails/month, Paris/Frankfurt residency, usage-based tx from $0.45/1k. Solo product teams pick Resend; marketing-led or EU-bound businesses pick Brevo. Compare Specs & Pricing →Amazon SES vs Brevo SES is raw $0.10/1k infrastructure you operate yourself; Brevo is a managed all-in-one (tx from $0.45/1k usage-based) with EU residency, a marketing suite, and a real support org. The ~4.5× rate premium buys deliverability handling, dashboards, campaigns, and someone to call. Compare Specs & Pricing →Brevo vs Mailjet The two French-rooted all-in-ones go head-to-head: Brevo offers the bigger free tier (9,000/mo vs 6,000), broader suite (CRM, WhatsApp/SMS), and cheaper usage rates ($0.45→0.25/1k); Mailjet counters with simpler plan bundles ($17.49 incl 15k) and a longer pure-email heritage. Both keep EU data processing under French jurisdiction — feature appetite decides it. Compare Specs & Pricing →Brevo vs Mailchimp Transactional (Mandrill) Mandrill is Mailchimp’s transactional engine priced in blocks ($0.80/1k falling to $0.40/1k at 4M+); Brevo is a full growth platform — EU residency, CRM, campaigns — with usage-based tx from $0.45/1k and a 9,000-email free tier. High-volume Mailchimp shops get synergy from Mandrill; most others get more platform per dollars from Brevo. Compare Specs & Pricing →Brevo vs MailerSend Both court small-to-mid teams, but from different ends: Brevo is an EU-hosted marketing+transactional suite with a 9,000-email free tier; MailerSend is a leaner email-focused platform starting at $7/mo incl 5k with polished suppression/split-testing tools. If campaigns and EU jurisdiction matter, Brevo; if you want focused email sending with modern UX, MailerSend. Compare Specs & Pricing →Brevo vs SMTP2GO SMTP2GO is focused outbound relay — free 1,000/mo, $15/mo Starter incl 10k, Professional bundling a dedicated IP — while Brevo is a full EU-hosted growth stack (free 9,000/mo, CRM, campaigns, tx from $0.45/1k). Relay pragmatists choose SMTP2GO; marketing-inclusive EU stacks choose Brevo. Compare Specs & Pricing →Scaleway Transactional Email vs SendGrid SendGrid is the Twilio-owned platform giant: $19.95/mo incl 50k then $0.199/1k, marketing suite, sub-users, global throughput. Scaleway is the sovereign utility: $0.291/1k ($0.233 on the $93.28/mo Scale plan past its 100k allowance), Paris residency, no plan fees below that tier. Cost and sovereignty favor Scaleway; platform depth and marketing favor SendGrid. Compare Specs & Pricing →Mailjet vs SendGrid Two combined tx+marketing platforms: Mailjet keeps EU processing with simple bundled plans ($17.49 incl 15k, $40.81 incl 50k) and approachable campaign tools; SendGrid brings Twilio-scale throughput, deeper sub-account architecture, and cheaper high-volume bands ($0.199 → $0.15/1k). EU compliance picks Mailjet; scale and ecosystem pick SendGrid. Compare Specs & Pricing →SendGrid vs Mailchimp Transactional (Mandrill) Mandrill’s prepaid blocks drop to $0.40/1k at 4M+ — undercutting even SendGrid’s $0.15/1k top band — but require whole-block purchases inside the Mailchimp account model. SendGrid spreads cost across monthly plans ($19.95 incl 50k → $89.95 incl 100k) and layers marketing automation, sub-users, and Twilio integration on top. Extreme tx volume favors Mandrill; platform breadth favors SendGrid. Compare Specs & Pricing →MailerSend vs SendGrid MailerSend wins the low end decisively ($7/mo incl 5k, friendlier console, built-in split testing); SendGrid wins scale economics and ecosystem ($19.95 incl 50k stepping to $0.15/1k, sub-users, Twilio channels). Below ~50k MailerSend is simpler and comparable-or-cheaper; beyond it, SendGrid’s bands and throughput pull ahead. Compare Specs & Pricing →SMTP2GO vs SendGrid Both sell SMTP-plus-API sending at scale. SMTP2GO keeps plans flat and bundles a dedicated IP at Professional ($75/mo incl 100k, $0.85/1k overage); SendGrid prices steeper entry ($19.95 incl 50k, then $89.95 incl 100k at $0.199/1k) but adds the marketing suite, sub-users, and the Twilio universe. Simple relay value favors SMTP2GO; platform breadth favors SendGrid. Compare Specs & Pricing →Scaleway Transactional Email vs Amazon SES The two cheapest options in the field split by jurisdiction and ops appetite: SES is $0.10/1k raw infrastructure you operate yourself; Scaleway is $0.291/1k managed-enough SMTP/API (300 emails included, Paris residency). EU-bound workloads or ops-light teams pick Scaleway; maximum-margin AWS-native stacks pick SES. Compare Specs & Pricing →Amazon SES vs Mailjet SES sells raw capacity at $0.10/1k with nothing included but pipes; Mailjet sells an EU-hosted product — plans bundling volume from $17.49/mo, campaign builder, segmentation, French data processing. The ~3–5× premium buys managed deliverability, UI tooling, and EU compliance rather than raw rate. Compare Specs & Pricing →Amazon SES vs Mailchimp Transactional (Mandrill) Mandrill is the cheapest managed block option ($0.80/1k falling to $0.40/1k) with Mailchimp integration; SES remains the absolute floor at $0.10/1k if your team operates its own deliverability stack. Between them sits a clear question: pay Mandrill for management + ecosystem, or keep 4–8× margin in-house on AWS. Compare Specs & Pricing →Amazon SES vs MailerSend MailerSend makes email someone’s easy job: $7/mo incl 5k, friendly console, suppression/split-testing tools — at $1.50/1k overage that dwarfs SES’s $0.10/1k. Teams with AWS fluency and cost pressure run SES; teams paying for engineer-hours instead pick MailerSend’s managed simplicity. Compare Specs & Pricing →SMTP2GO vs Amazon SES Both keep sending cheap, differently: SES is $0.10/1k DIY infrastructure inside your AWS bill; SMTP2GO is managed relay — free 1,000/mo, $15/mo Starter incl 10k, Professional $75/mo incl 100k with a bundled dedicated IP. Ops-heavy teams save real money on SES; everyone else pays SMTP2GO’s small premium to never think about it. Compare Specs & Pricing →Scaleway Transactional Email vs Mailchimp Transactional (Mandrill) Scaleway is sovereign utility pricing: $0.291/1k ($0.233 on the $93.28/mo Scale plan past 100k), Paris residency, nothing else. Mandrill is Mailchimp-integrated blocks from $0.80/1k down to $0.40/1k at massive volume. Across typical volumes Scaleway stays dramatically cheaper; beyond ~1M/month Mandrill’s block ladder closes in — but never offers EU residency. Compare Specs & Pricing →Scaleway Transactional Email vs MailerSend A budget matchup decided by geography and tooling: Scaleway wins on raw price ($0.291/1k pay-as-you-go, EU sovereignty); MailerSend wins on product polish ($7/mo entry, template editor, suppression/split-test tools) while charging 6× the per-1k at the margin. Minimalist EU senders pick Scaleway; teams wanting built-in tooling pick MailerSend. Compare Specs & Pricing →Scaleway Transactional Email vs SMTP2GO Two lean outbound specialists: Scaleway undercuts on rate ($0.291/1k pay-as-you-go, EU residency); SMTP2GO answers with global anycast SMTP ingress, a 200/day-capped free tier, and a dedicated IP bundled at Professional ($75/mo incl 100k). Cost-and-sovereignty favor Scaleway; global relay ergonomics and IP inclusion favor SMTP2GO. Compare Specs & Pricing →Mailjet vs Mailchimp Transactional (Mandrill) Both carry French heritage (Mailjet HQ; Mandrill under Mailchimp/Intuit) but diverge sharply: Mailjet bundles EU-hosted tx + newsletter campaigns from $17.49/mo incl 15k; Mandrill sells pure transactional blocks ($0.80→0.40/1k) woven into Mailchimp. Campaign-inclusive EU stacks pick Mailjet; high-volume Mailchimp-centric transactional picking favors Mandrill. Compare Specs & Pricing →Mailjet vs MailerSend Approachable platforms with different anchors: Mailjet anchors on EU jurisdiction and bundled marketing ($17.49 incl 15k + campaign suite); MailerSend anchors on low-cost focused email ($7/mo incl 5k, polished UX, split testing). Choose Mailjet for EU-hosted campaigns in one tool; choose MailerSend for lean, modern sending. Compare Specs & Pricing →Mailjet vs SMTP2GO SMTP2GO is focused global relay (free 1,000/mo, $15 Starter incl 10k, Professional with included IP); Mailjet adds an EU-hosted marketing layer (campaigns, segmentation, French processing) from $17.49/mo incl 15k. Pure outbound value leans SMTP2GO; EU-compliant tx+marketing bundles lean Mailjet. Compare Specs & Pricing →MailerSend vs Mailchimp Transactional (Mandrill) MailerSend bills plans ($7/5k → $35/50k, $1.30–1.50/1k overage) with a modern UX; Mandrill bills prepaid blocks ($0.80→0.40/1k) inside Mailchimp. Low-volume senders get far more included value from MailerSend; million-plus senders unlock Mandrill’s block discounts — accepting whole-block expiry and the Mailchimp orbit. Compare Specs & Pricing →SMTP2GO vs Mailchimp Transactional (Mandrill) Mandrill monetizes Mailchimp synergy via blocks ($0.80→0.40/1k); SMTP2GO monetizes global relay simplicity via plans (free 1,000/mo, $15 incl 10k, $75 incl 100k with dedicated IP). Outside the Mailchimp ecosystem, SMTP2GO’s included volumes beat Mandrill at low-mid volume; deep-volume Mandrill discounts win past ~1M/month. Compare Specs & Pricing →MailerSend vs SMTP2GO Two SMB-friendly senders with different shapes: MailerSend pairs a modern console with continuous volume-slider pricing ($7/5k → $35/50k, $1.30–1.50/1k overage); SMTP2GO uses flat steps (free 1,000, $15/10k, $75/100k) with a dedicated IP bundled at Professional and anycast global SMTP. Product polish favors MailerSend; relay pragmatism and IP inclusion favor SMTP2GO. Compare Specs & Pricing →

8. Frequently Asked Questions
What is the main pricing difference between transactional and marketing email APIs?
Transactional emails (password resets, order confirmations, receipts) require immediate sub-second delivery and dedicated high-reputation IP pools, typically priced per 1,000 sent emails. Marketing emails (newsletters, promotional broadcasts) are sent in large batches, often priced by contact list size or higher per-thousand rates with visual template builders and campaign management tools.
When should I purchase a dedicated IP address?
A dedicated IP is recommended when sending consistently over 100,000 emails per month. A dedicated IP isolates your sender reputation entirely from other senders, preventing third-party spam spikes from hurting your inbox placement. For lower or sporadic volumes, high-reputation shared pools (like Postmark or Resend) generally deliver better inbox rates than an un-warmed cold dedicated IP.
Why is Amazon SES so much cheaper than Postmark, SendGrid, or Resend?
Amazon SES operates as raw cloud infrastructure at $0.10 per 1,000 emails with zero managed features. Specialized providers like Postmark ($1.25/1k), Resend ($0.40/1k), Mailgun ($35/mo covering 50k then $0.25–0.35/1k), and SendGrid ($0.25/1k) bundle deliverability monitoring, automatic IP pool warm-up, visual template designers, webhooks, React Email SDKs, and 30–45 days of searchable message logs.
How does European data sovereignty affect email API choices?
Under EU GDPR, sending personal data (email addresses, message contents) through US-headquartered clouds can expose companies to CLOUD Act compliance issues. Providers like Brevo, Scaleway, and Mailjet maintain primary datacenters in France and Germany with strict European data isolation and ISO 27001 compliance.
Do email API free tiers renew every month?
Yes, Brevo provides 9,000 emails/month (300/day), Resend offers 3,000 emails/month, and Scaleway includes 300 emails on pay-as-you-go before its USD-equivalent usage rate applies. AWS SES has no standing free allowance — it is pay-as-you-go. Postmark and SendGrid provide one-time trial allowances (100 emails) before paid tiers apply.
How does currency conversion work in this comparison calculator?
Vendors priced natively in Euros (Brevo, Scaleway, Mailjet) are normalized using the fixed benchmark conversion rate of 1 EUR = 1.166 USD (captured 2026-08-27). The comparison uses one USD display currency; check the linked vendor sheet for the final invoice currency.
