SMTP connector

Send transactional and broadcast email from PushFire through your own mail server. Unlike Resend, SMTP authenticates as one From email — that address is the SMTP login and what recipients see.

Open Connectors and select SMTP.

• A mail server that accepts SMTP with TLS on port 465
• The From email and password for that address. Google Workspace and Gmail require an app password, not the account password.
• A From name recipients should see

1. Enter the From name and From email. Recipients see From name and From email in their inbox. The From email is also the SMTP login — this connector cannot send as a different address.
2. Enter the SMTP host (for example smtp.gmail.com). PushFire currently supports a single port: 465 with TLS.
3. Enter the password. For Google Workspace and Gmail, use an app password.
4. Set a connector name. Recipients never see it. You will type this name to confirm delete.
5. Select Connect SMTP. PushFire does not send a test email. The first real send is the proof.

PushFire currently supports one SMTP port: 465 with TLS. Ports 25 and 587 are not available. Enable SSL/TLS on 465 on your mail server. If the server only accepts another port, this connector cannot send.

SMTP authenticates as the From email you connect. You cannot add a second From on this connector the way you can with a verified Resend domain. To send as a different address, delete this connector and create a new one.

From name, From email, host, and password are written once. There is no edit or rotate path. To change any of them, delete this connector and create a new one.

• Host: smtp.gmail.com
• From email: the Google account address
• Password: an app password. The Google account password will not work.

After you connect, the page shows a Connector ID and a Sender ID. Include both on each API send so the request uses this connector and this From. SMTP has exactly one sender.

• Email Layouts — create reusable HTML templates
• Broadcast Email Notifications — send one-off email campaigns
• Email Notification nodes in workflows

• Connection failed or TLS error — the server is not accepting port 465 with TLS. Ports 25 and 587 are not supported.
• Authentication failed — for Google, use an app password and confirm SMTP is enabled for the account.
• Rejected From — the send used a different address than the From email on this connector.
• Connected but mail never arrived — PushFire does not test on connect. Send a broadcast or workflow email and check the subscriber status.
• Need to change From, host, or password — delete this connector and create a new one.
