01Understand subscriber statuses
Every address you send to becomes a subscriber in your account, with one of four statuses:
| Status | What it means | Can you send? |
|---|---|---|
| Verified | The address checked out as deliverable, or you approved it. | Yes |
| Unverified | The address hasn't been checked yet. | Verified first, then sent |
| Caution | The check couldn't confirm the address is safe to send to. | No, until it's approved |
| Invalid | The address doesn't exist or has bounced. | No, it's blocked |
02Let verification run on send
When you send to an address MailEnv hasn't seen, or one that's still unverified, MailEnv verifies it before delivering. The API responds with 201 and a queued_for_verification status, and the message sends once the address checks out.
Sends to caution or invalid addresses are refused with a 403, so a bad address never reaches Amazon SES or counts against your bounce rate.
03Review your subscribers
Open Subscribers to see everyone in your account, with a count for each status at the top. Search by email, first name, or last name.
Each Email List shows the same status breakdown for just its members, so you can see how healthy a list is at a glance.
04Verify addresses by hand
On Subscribers or an email list, click the Unverified (Verify) badge next to an address. The Verify Subscriber window shows your credit balance and confirms the check will use one credit. MailEnv checks the address and updates its status right away.
An address can only be verified once. After that it stays verified, caution, or invalid.
05Get caution addresses approved
A caution result isn't a definite no, but MailEnv won't send to the address until it's approved. If you know the person, for example a customer who just signed up through your app, contact us and we can approve it. Approving marks the address verified and doesn't use a credit.
06Keep enough verification credits
Verification uses credits, one per address. Your balance shows in the Verify Subscriber window. To buy more, open the account menu and choose Verification Credits.
If you're out of credits, manual verification stops with an "insufficient verification credits" message. Top up before a big send so new addresses aren't held up.
