Every Email2Phone feature, in one place
If you are comparing alerting tools by their spec sheets, this is ours: five short tables. Each row is one capability, what it does, and a link to the Help article that explains it. The prose version is how an email turns into a call, step by step.
Checked against the product on 11 September 2026.
Delivery and acknowledgement
| Capability | What Email2Phone does | Help |
|---|---|---|
| How alerts get in | Anything that can send an email sends it to your @email2phone.net address. No integration to install. |
Getting started |
| What the call is | Your phone rings and says how many messages are waiting; press 1 and a voice reads each one, subject then body. Any phone: mobile, landline or VoIP, in any country. | Countries |
| A burst of alerts | One call. The call announces how many unacknowledged messages are waiting and reads them in turn; 80 emails at once is one phone call. | One call for many emails |
| Acknowledgement | The listener presses 8 to save, 7 to delete or 5 to reply. That key press is the acknowledgement. | The keypad |
| Callbacks when nobody presses a key | On a phone with voicemail switched off, Email2Phone calls back at 5, 15, 30, 60 and 60 minutes, five attempts, then files the message in Message History. | If nobody answers |
| Voicemail | If voicemail picks up, the message is left there and counts as delivered; no callbacks follow. Put critical alerts on a number with voicemail off. | Voicemail |
| Escalation | Several numbers, dialled one after another or all at once. Stop at the first acknowledgement, or carry on until everyone has been called; a voicemail pickup counts as accepted for that setting. | More than one phone |
Routing and control
| Capability | What Email2Phone does | Help |
|---|---|---|
| Filters | One condition each, on From, To, CC, Subject or Body (equals, contains, begins, ends, matches). Action: ignore the email, or call the phones you tick. | Filters |
| Default number | Any email no filter excludes rings the default number. A number that is not default rings only when a filter calls it. | Filters |
| Quiet hours | Per phone number, not per filter. A message that arrives inside a number's quiet window is not delivered to that number and is readable in Message History. | Quiet hours |
| Suspended Delivery | One account switch for maintenance windows. Mail that arrives while it is on is not delivered later; it is readable in Message History. | Suspended Delivery |
| Spam | An account toggle files what its spam check rejects under SPAM in Message History; filters act as a second layer. | Spam |
| Flood control from the handset | On a call, 9 then 1 blocks the sender and creates the filter; 9 then 3 deletes every unread message from that sender. | The keypad |
Retrieval and reply
| Capability | What Email2Phone does | Help |
|---|---|---|
| Dial-in replay | Call an access number in the US, Canada or the UK, enter your six-digit PIN, hear new and saved messages. Free on every plan, trial included. | Listening again |
| Spoken reply | Press 5, record after the tone, press #. The sender gets an email with a link to the recording. | Replying by voice |
| Message History | Messages nobody acknowledged, and messages not delivered because of quiet hours or Suspended Delivery, are kept in your online account to read. | If nobody answers |
| Attachments | The call announces an attachment and plays it if it is a .WAV file. | Attachments |
Sources and phones
| Capability | What Email2Phone does | Help |
|---|---|---|
| Sources | Your @email2phone.net address is what triggers calls. Mailboxes you connect (Gmail, Yahoo, AOL, Microsoft 365 and others, no fixed limit) are read when you dial in and never trigger a call. |
Connecting a mailbox |
| Monitoring tools | Anything with an email notification: Nagios, Zabbix, PRTG, UptimeRobot, a Synology NAS, Microsoft 365 rules, temperature sensors. | Setup guides |
| Phones | Mobile, landline or VoIP, any country. One credit covers up to 60 seconds to a US or Canadian number; other countries are 1 to 6 credits a minute. | Countries |
Plans
| Capability | What Email2Phone does | Help |
|---|---|---|
| Pricing | $10 a month for 40 credits, $100 for 500, $400 for 3,000. Extra credits $0.25, $0.20 or $0.15. Priced by credits, not by user. | Pricing |
| What a credit counts | One credit per phone called. An alert that rings three phones at once uses three credits; sequential dialling that stops at the first acknowledgement uses one per phone actually rung. | Billing |
| Trial | 30 days, up to three emails a day delivered as calls, dial-in included, no credit card. A trial account can add a second phone and create filters. | Free trial |
| Terms | No setup fee, no contract, first month prorated. In operation since 2008. | Billing |
What it does not have
- No SMS or MMS; calls only.
- No API or webhook; email in, call out.
- No mobile app.
- No on-call rotations, incident timeline or response-time analytics.
- No per-message throttle setting, because a burst of emails is already one call.
If one of those is the feature you need, an on-call platform is the right tool and this is not. The full list, with what to use instead, is in What Email2Phone does not do.
