SMTP connector

Connectors

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.

Prerequisites

  • A mail server that accepts SMTP on a host-allowed port (465 with TLS, or an alternate such as 2525 / 2587 with STARTTLS)
  • 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

Configuration

  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 and port (default 465). Encryption is TLS on 465 and STARTTLS on other allowed ports. Ports 25 and 587 are rejected.
  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.

Port

PushFire stores the port you enter. Default is 465 with TLS. The host blocks outbound 25 and 587 — those values are rejected in the form and at create. Use 465 (Gmail / Google Workspace) or your provider’s alternate port (2525, 2587, 2465). Encryption is derived: 465 → TLS, any other allowed port → STARTTLS.

One From email

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.

Locked after you connect

From name, From email, host, port, 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.

Google Workspace and Gmail

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

API IDs

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.

After setup

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

Troubleshooting

  • Connection failed — check host, port, and that the port is not 25 or 587. On 465 the server must accept implicit TLS. On 2525 / 2587 it must accept STARTTLS.
  • 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.
