# I can’t send email

Your email gets stuck in the outbox, or you get an error when you send. Start with the cause at the top.

## Right guide?

- Does your email arrive but end up in the spam folder?

## Common causes

### 1. It says `authentication failed` or that the password is wrong

**Check:** The outgoing server requires login. Does the app have the right username and password?

**What to do:** Use the full email address as the username and turn on login for the outgoing server (SMTP).

### 2. Email gets stuck in the outbox

**Check:** Does the app have the right server and port for outgoing email?

**What to do:** Use `mail.inleed.com`, port 465 with SSL/TLS.

### 3. It worked before but stopped after a move or upgrade

**Check:** Is the app using an old server name?

**What to do:** Change the server name to `mail.inleed.com`.

### 4. Nothing works at home, but it works on your phone

**Check:** Is the IP address blocked after failed logins?

**What to do:** Whitelist your IP address.

### 5. You’ve sent a lot of email today and now it doesn’t work

**Check:** Has the address reached its limit for emails per day?

**What to do:** The limit applies per day. For newsletters, use a mailing tool such as Inleed Mailer.

### 6. Webmail can’t send either

**Check:** Is the hosting suspended, for example because of an unpaid invoice?

**What to do:** Follow the guide for a suspended service.

## Good to know

- Try sending from [webmail](https://mail.inleed.com/). If that works, the problem is in the app’s settings.
