Worth knowing before you set it up rather than after.
- No text messages. Email2Phone delivers email as a voice call.
- No API and no webhook. Email in, call out. That is a limitation and also the reason the list of things that can trigger a call is as long as it is: anything that can send an email already integrates.
- No mobile app. The phone that rings can be a mobile, a landline, a desk phone or a VoIP line; nothing is installed on any of them.
- No on-call rotation management, incident timeline or incident analytics. There are no rotations, no MTTA or MTTR reporting and no handover. If you need those, an incident platform is the right purchase and this is not a substitute; the alternatives pages say when to stay with one.
- No per-message throttle setting. There is no rate limit to configure, because the mailbox model makes one largely unnecessary: a flood becomes one call rather than a queue of them.
If what you need is a phone that rings, calls back when nobody answers, and, on a line with voicemail off, counts nothing as delivered until a person presses a key, that is the whole product; how an email becomes a phone call, the long version has all of it.
