SMTP2GO
Pros
- + Permanent free plan: 1,000 emails/month with no time limit
- + 100% delivery SLA in the terms (deliver or refund) plus 30-day money-back guarantee
- + Multi-region routing with best-path selection across ~10 locations in US/EU/APAC
- + Deliverability tooling included on all plans: DKIM/SPF automation, feedback loops, blacklist and spamtrap monitoring
- + Clear real-time reporting and bounce/spam tracking; 20-year operating history, bootstrapped
Cons
- - Dedicated IP requires the $75 Professional tier — a steep jump from Starter
- - Professional overage bills above the in-plan per-message rate
- - Free plan limits: 200/day, 25/hour until domain verification, 5 days reporting, ticket support only after 14 days
- - Reporting retention short by default (30 days); longer storage is a paid add-on
- - Scale ceiling versus the large API platforms at tens of millions of emails per month
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
