Mailgun combines email sending with routing and validation functions. The April 2026 snapshot lists Free, Basic, Foundation and Scale with different sending volumes and feature allowances. Compare the exact current package rather than assuming all functions are included in the entry price.
Resend provides email APIs, SMTP support and React Email tooling. The April 2026 record lists a Free allowance of 3,000 emails monthly with a separate 100-per-day cap. Paid volume options increase sending and domain allowances; current terms should be checked.
SendGrid offers email sending and a separate marketing product within the Twilio family. The April 2026 fetch did not establish current pricing. Its stored Essentials and Pro rates are estimates, and the zero-price row is described as a trial rather than a confirmed permanent free plan.
SMTP2GO lists Starter 10K at $15 monthly and Professional 100K at $75 monthly, checked October 3, 2026. Annual base subscriptions cost $150 and $750 upfront; email allowances still reset monthly. Free accounts have both a monthly allowance and a daily cap.
