Resend
Pros
- + Transparent, opt-in-overage pricing ladder from a real free tier up to 2.5M emails/month
- + React Email component library solves the worst part of building transactional templates
- + Four AWS sending regions with per-domain routing, plus SMTP relay and official SDKs
- + SOC 2 Type II, GDPR documentation, and DKIM/SPF/DMARC handled automatically
- + Recipient-counting and quota rules are documented plainly, including the free plan's 100/day cap
Cons
- - All account data is stored in the US regardless of sending region — no EU data residency
- - 30-day data retention ceiling on every self-serve plan
- - Uptime SLA (99.99%) is Enterprise-only and sales-negotiated
- - Shared sending infrastructure means shared IP reputation unless you buy the dedicated IP add-on
- - Short track record as a company (incorporated January 2023)
Mailgun
Pros
- + Inbound email parsing on every plan, including Free — the strongest developer-side feature in this category
- + Published four-tier pricing with explicit overage rates ($15/$35/$90 per month tiers)
- + Credit-backed 99.99% availability SLA on API, SMTP, and outbound delivery
- + US or EU (Ireland) sending regions per account, with GDPR/HIPAA/SOC/ISO 27001 compliance paperwork
Cons
- - One day of log retention on Free and Basic — debugging old delivery issues is impossible without exporting logs
- - Chat and phone support only on the $90/month Scale tier; support quality under Sinch ownership draws community criticism
- - Dedicated IPs cost extra below high volumes (third-party listings quote ~$59/IP/month)
- - US operating entity under a Swedish parent — CLOUD Act exposure remains for privacy-sensitive EU buyers
