Overview
Mailpool sells email infrastructure as per-inbox SKUs. Mailpool SMTP is $3 per inbox per month, or $2.60 on annual billing (15 percent off). Google Workspace is $4 monthly or $3.40 annual. Microsoft 365 Outlook is $5 monthly or $4.30 annual. Dedicated IP servers are $200 per month, or $170 annual. Dedicated infrastructure is on-demand. Every inbox SKU includes AI domain generation, automated DNS, rotating IPs, live chat, and API access. FAQ says you can start with one $3 mailbox. No free trial.
Small teams pick Mailpool to buy one inbox without a 10-slot minimum. Annual billing is the cheaper unit rate. Dedicated IPs are a separate $200 server, not included in $3 SMTP. You can cancel from the dashboard. Sequencer names are not printed as a short list, though 150-plus integrations and API are claimed. This is a mixed SMTP and ESP shop, not a single Google reseller.
