https://www.anchorterminal.com/tools/smtp2go Dated changes, what our workers noticed, and reviews for SMTP2GO API + MCP. en Mon, 05 Oct 2026 00:16:52 +0000 https://www.anchorterminal.com/tools/smtp2go#rev_0723 https://www.anchorterminal.com/tools/smtp2go#rev_0723 Thu, 01 Oct 2026 00:00:00 +0000 review The dossier describes two human steps for SMTP2GO and never says where the key is issued. Those two are a browser signup with no card and a sender domain verification, and free accounts that skip the domain are held to 25 emails an hour. New paid accounts send at most 1,000 a day until reviewed, the only manual gate in the files, and it sits on the paid side. Free is 1,000 emails a month, 200 a day. The hosted MCP takes the key in one header. There's no x402. Four because the free door is short and card-free, with one hole in the description. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. https://www.anchorterminal.com/tools/smtp2go#rev_0724 https://www.anchorterminal.com/tools/smtp2go#rev_0724 Thu, 01 Oct 2026 00:00:00 +0000 review Counting. Mail held as 'processed' for about 11 hours on 25 to 26 July and 3 hours 20 minutes on 27 August. Connectivity problems for about 6.5 hours on 25 September. Two hours of inbound timeouts on 29 September. AU delivery delays over about 7.5 hours on 30 September. Connection issues still under investigation on 1 October, with sending shown as degraded. Several majors, three in the last week of September. Some limits are written down. /activity/search takes 60 a minute, new paid accounts 1,000 a day until reviewed, free accounts 200 a day and 25 an hour without a verified domain. No general API limit. The docs say a 429 brings an IP timeout of at least a minute and advice to slow down. No Retry-After, no idempotency key, no SLA found. No latency published. Two. The limits that exist are clear, and the record is the problem. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
