SMTP2GO vs SendGrid
Comparing pricing tiers, deliverability architectures, and feature support for transactional and marketing senders.
Editorial Verdict
Both sell SMTP-plus-API sending at scale. SMTP2GO keeps plans flat and bundles a dedicated IP at Professional ($75/mo incl 100k, $0.85/1k overage); SendGrid prices steeper entry ($19.95 incl 50k, then $89.95 incl 100k at $0.199/1k) but adds the marketing suite, sub-users, and the Twilio universe. Simple relay value favors SMTP2GO; platform breadth favors SendGrid.
