Plunk
Pros
- + Dead-simple pricing: free at 1,000 emails/month, then $0.001/email with no base fee and per-category spend caps
- + AGPL-3.0 open source with free self-hosting via Docker — full data ownership and an exit path
- + Transactional, campaigns, workflows and inbound email in one product with unlimited contacts on every plan
- + EU-hosted and GDPR-focused, with DKIM/SPF/DMARC configured automatically on custom domains
- + SMTP relay plus a language-agnostic REST API; email validation and real-time analytics built in
Cons
- - No published uptime SLA or deliverability guarantees; sending IP reputation unproven at scale
- - Small team and young product (2022) versus incumbents with a decade of sending history
- - Hosted platform is EU-only; no dedicated IP or managed IP warm-up offering (the DB's IP warming claim is wrong)
- - AGPL-3.0 copyleft matters if you embed the software in a commercial product
Amazon SES
Pros
- + Lowest published per-email rate: $0.10 per 1,000 emails, no plan required
- + Same-region integration with EC2, Lambda, IAM, and CloudWatch
- + Transparent pricing page covering add-ons and plan bands
- + Global Endpoints for multi-region sending resilience
- + Scales to very high volume without provisioning infrastructure
Cons
- - Sandbox start (200 messages/day to verified recipients) with an opaque production-access review
- - No marketing tooling, templates, or dashboards — it is a pipe, not a suite
- - Dedicated IPs, attachments, and deliverability add-ons inflate the real bill
- - Deliverability and IP warm-up are your responsibility
