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
MailChannels
Pros
- + Solves the shared-IP reputation problem for multi-tenant hosts — one compromised account no longer gets the whole network blocklisted
- + Published, volume-based pricing with a free Email API tier of 3,000 emails per month
- + Long track record since 2004 with named large hosts (DreamHost case: email tickets from ~300/week to ~10)
- + Compromised-account detection and spam-trap handling built for hosting abuse patterns, not generic sending
Cons
- - Starter tier excludes API, webhooks, and the cPanel plugin — practical integrated entry is Standard at $524.99/month
- - No published uptime SLA and no 24/7 support line on any tier
- - Shared IP pools only; dedicated IPs are not a standard option
- - B2B pricing and product scope make it a poor fit for individual developers and small senders
