What is Specify Connection?

Specify Connections (also called multi-routing) is how SMTPPai decides which connection sends which kind of email. You can keep one provider for everything, or split WordPress transactional mail, WooCommerce, Newsletter, and Outreach across different connections.

Why it exists

SMTPPai lets you save many connections (Amazon SES, Mailgun, Postmark, Gmail, Outlook, and more). Without routing, WordPress has no clear rule for which connection should send:

• a password reset
• a WooCommerce order email
• a newsletter campaign
• an outreach message

Specify Connections makes that choice explicit, so every send path is intentional, testable, and visible in the Email Log.

Where to open it

Go to SMTPPai → Specify Connections.

Mode 1: One for Everything

Use this when one provider and one From identity are enough.

1. Open Specify Connections.
2. Select One for Everything.
3. Choose the connection that should send all mail.
4. Save.

This is the basic setup. When you create your first ready connection, SMTPPai can auto-assign it for you, so WordPress mail starts using your provider right away.

Best for: small sites, one brand From address, one mail provider.

Mode 2: Use Separate Connection (Recommended)

Use this when different mail streams need different providers, From addresses, or reputation boundaries.

1. Open Specify Connections.
2. Select Use Separate Connection (Recommended).
3. Assign a connection to each route row you use.
4. Save.

Why “Recommended”? Transactional mail, store receipts, newsletters, and outreach have different risk and volume profiles. Separating them keeps failures, bounces, and provider reputation from mixing into one shared path.

Routes you can assign

How multi-routing helps delivery

1. WordPress (or MailPai) prepares a message for a route.
2. SMTPPai picks the connection assigned to that route.
3. The provider API or SMTP session sends the message.
4. Email Log records the result, connection, and route.

That path is more effective than a single connection because each stream can use the right provider, From identity, and quota.
