Domain & authorized senders

Start here: E-mail — documentation hub.

Before Routee accepts a transactional email (HTTP or SMTP), your sending domain must be verified and your From address must be an authorized sender on that domain.

Configure everything under Email → Domains on go.routee.net.

Why domain verification matters

Step 1 — Add a domain

1. Open Email → Domains → Add domain.
2. Enter the domain you will use in From addresses (e.g. yourdomain.com).
3. Routee generates SPF and DKIM DNS records for that domain.

Step 2 — Publish DNS records

SPF

Include Routee in your SPF record so receiving MTAs accept mail from our infrastructure:

v=spf1 mx include:email.routee.net ~all

Merge with your existing SPF if you already have one — only one SPF TXT record per domain is allowed.

DKIM

Add the TXT record Routee provides, typically:

Routee signs outbound mail with selector routee. Receiving servers fetch this public key to verify signatures.

Optional — DMARC

After SPF and DKIM work, consider a DMARC policy on _dmarc.yourdomain.com to monitor or enforce alignment. Routee docs do not require DMARC for verification, but it improves deliverability monitoring.

Step 3 — Verify the domain

1. Wait for DNS propagation (minutes to 48 hours depending on TTL).
2. Click Verify on the domain row in the portal.
3. Status changes to Verified when SPF and DKIM checks pass.

Until verified, sends using @yourdomain.com addresses are rejected.

Step 4 — Authorized senders

Each From address must be explicitly authorized:

1. On the domain detail page, open Authorized senders.
2. Add an email address (e.g. [email protected]).
3. Routee sends an invitation email with a personalized link (valid 72 hours).
4. The recipient clicks the link → status becomes Verified.

You can resend the invitation if it expires. At least one verified sender is required before the account can send.

SMTP credentials (after setup)

Once domain and sender are ready, use Connect application credentials for SMTP:

• Host: smtp10.amdtelecom.net
• Username / password: Application Id / Application Secret
