SecureSMTP vs SMTP2GO
SMTP2GO is a solid, no-surprises SMTP relay — they’ve been around since 2006. SecureSMTP covers the same job with a modern UI, a WordPress plugin that beats SMTP2GO’s community plugin, and a hosted form builder if you need it.
Modern relay + WordPress plugin + form builder + real-time dashboard. Cream and tangerine brand, opinionated UX, built for site owners in 2026.
Battle-tested SMTP relay with per-mail pricing and generous free tier (1,000/month). Traditional dashboard, community-maintained WordPress plugin.
TL;DR
SMTP2GO’s free tier is the most generous in the market at 1,000 emails/month. If you’re sending that little and just need a relay, they’re a great pick.
SecureSMTP wins if you want an integrated form builder, spam filtering baked in, or an official WordPress plugin instead of a community one. And once you’re past 1k emails, our $5/mo entry plan beats their $10/mo Starter.
