SendGrid SMTP and IMAP settings
SMTP relay settings for SendGrid, where the username is the literal string apikey.
Outgoing mail (SMTP)
| SMTP server | smtp.sendgrid.net |
|---|---|
| Port | 587 (STARTTLS) or 465 (SSL/TLS) |
| Username | The literal string: apikey |
| Password | See authentication note below |
Authentication
The SMTP username is literally the word apikey for every account. The password is a SendGrid API key with Mail Send permission. Ports 25 and 2525 also work.
How to set up SendGrid in your email tool
- Open your email client or sending tool and add a new account.
- For outgoing mail, enter the SMTP server smtp.sendgrid.net on port 587 (STARTTLS) or 465 (SSL/TLS).
- Set the username to the literal string: apikey, and use the password described in the authentication note above.
- Save the account and send a test email to confirm it works.
Connecting is the easy part. Landing in the inbox is not.
Once SendGrid is connected you can send, but whether your cold email reaches the inbox depends on SPF, DKIM, and DMARC authentication, your sender reputation, and proper domain warmup. Scheduler Zero handles warmup and deliverability so your emails actually land.
