- `email/smtp2go` | qualifies-with-caveat | evidence documented | binding request-rate | category transactional sender and SMTP relay
- needs card no, phone yes, ID no, institution no | verified 2026-10-30T09:26:49.192Z (live) | stale on 2026-11-30

- free tier: 1,000 emails/month, 200/day, and 25/hour until a sender domain is verified | unit: requests | metered on: request-count | read on: 2026-10-22 | source: [1] | note: Sends above the daily limit are queued and released as the daily quota allows; past 1,000 in a month further sends are rejected. Up to 5 sender domains or single sender emails can be verified, and while no sender domain is verified the account is held to 25 per hour. A send from an unverified sender is rejected and still counts toward the monthly quota. Reporting covers the past 5 days, and support is ticket-only after 14 days. The free plan's page names no restriction on recipients.
- per-object cap: not applicable
- retention: 5 days of reporting on the free plan, against 30 on paid | source: [2]
- egress: not applicable: an outbound sender | metered: no | source: [2]
- identity: any-phone | detail: The free-plan signup asks for a work email at a private domain (addresses at public domains such as Gmail and Yahoo are refused), a full name, a company, a password and a contact phone number verified by a 5 digit SMS code; no card. Sending needs a verified sender domain or a verified single sender email, and a Gmail address cannot be verified as a single sender, so in practice the account needs a domain the sender controls.
- interface: rest, cli
- limits:
  - request-rate (binding): 200 emails per day [1]
  - request-rate (binding): 25 per hour while no sender domain is verified [1]
  - request-rate (binding): 1,000 emails per month [1]
- binding note: 25/hour is 600/day if sustained and is the first ceiling a new signup meets, before the 200/day or the 1,000/month.
- interface detail: SMTP and the SMTP2GO API
- tooling: any SMTP client
- composes with: a 200/day relay with an hourly floor, so it composes with a sender that bursts rather than one that schedules.
- reliability: new paid accounts are held at 1,000/day during a one-time review
- notes: Three stacked caps on one product, and the hourly one is on the developer page but not on the pricing table.
- evidence note: no message was sent, so no delivery is proved. The submission path was probed: mail.smtp2go.com:2525 answered 250, STARTTLS completed, and AUTH LOGIN returned 334
