# Email verification API

> Verify a single address in real time.

Base URL: `https://api.emailit.com/v2`. Authenticate with `Authorization: Bearer <API key>`.

## Verify an address — POST /email-verifications

> Check one email address in real time: syntax, disposable and role addresses, MX records and, in full mode, the mailbox itself.

# Verify an address

Verifies one email address and returns the result in the response. Each verification costs 5 credits, charged before the check runs. To verify many addresses at once, [create a verification list](/docs/api-reference/email-verifications/lists/create/). Requires an API key with `full` scope.

`POST /email-verifications`

## Request body

- `email` (string, required): Address to verify. A value that isn't a valid address still returns `200`, with `result: "invalid"` and a score of `0`, and is charged.

- `mode` (string): `fast` (default) checks syntax, disposable and role-based addresses, free providers, gibberish, MX records and domain age. `full` also connects to the recipient's mail server to check whether the mailbox exists, is disabled or is full, and whether the domain accepts all addresses. In `fast` mode, the mailbox checks are `null`.

## Returns

Returns `200 OK` with an `email_verification` object. Emailit also sends an [`email_verification.created`](/docs/webhooks/events/email-verification/created/) webhook event.

| Status | When |
| --- | --- |
| `400` | `email` is missing or `mode` isn't `fast` or `full` (standard validation error). |
| `402` | The workspace doesn't have 5 credits left. The body is `{"error": {"message": "…", "code": 402}}`. |

### Result

| `result` | Meaning |
| --- | --- |
| `safe` | Passed every check and scored 70 or more. |
| `invalid` | The syntax is invalid or the domain has no MX records, so it can't receive email. |
| `disposable` | The domain belongs to a disposable email service. |
| `disabled` | The mailbox exists but is disabled. `full` mode only. |
| `inbox_full` | The mailbox is full. `full` mode only. |
| `role` | A role-based address such as `info@` or `support@`. |
| `unknown` | No check failed, but the score is below 70. |

### Score and risk

`score` runs from `0` to `100`. `risk` is `high` when the syntax is invalid, the domain has no MX records, the address is disposable or the mailbox is disabled. Otherwise it follows the score: `low` from 80, `medium` from 50, and `high` below 50.

### Fields

- `status` (string): `completed` for single verifications.

- `checks` (object): Individual checks: `valid_syntax`, `disposable`, `role_account`, `free_email`, `gibberish` and `has_mx_records` (booleans), `domain_age` (age of the domain in days, or `null` if unknown), and the `full`-mode checks `smtp_connect`, `deliverable`, `disabled`, `inbox_full` and `catch_all` (`null` in `fast` mode).

- `address` (object): The address split into `mailbox`, `domain`, `suffix` (the part after `+`, or `null`) and `root` (the address without the suffix).

- `did_you_mean` (string | null): Suggested correction for a likely typo, for example `ada@gmail.com` for `ada@gmial.com`.

- `mx_records` (object[]): The domain's MX records, each with `priority` and `exchange`.
