MailerSend vs SMTP2GO

Comparing pricing tiers, deliverability architectures, and feature support for transactional and marketing senders.

Editorial Verdict

Two SMB-friendly senders with different shapes: MailerSend pairs a modern console with continuous volume-slider pricing ($7/5k → $35/50k, $1.30–1.50/1k overage); SMTP2GO uses flat steps (free 1,000, $15/10k, $75/100k) with a dedicated IP bundled at Professional and anycast global SMTP. Product polish favors MailerSend; relay pragmatism and IP inclusion favor SMTP2GO.
