Built for This Email Workflow

Use SMTP infrastructure, authentication and monitoring appropriate to your sending requirements.

Inventory Your Email

Document applications, domains, message types and current sending volumes before changing providers.

Preserve Suppressions

Keep bounce, unsubscribe and suppression information so invalid or opted-out recipients are not accidentally mailed again.

Rebuild Authentication

Configure and verify SPF, DKIM and DMARC for the new sending environment.

Update Integrations

Change SMTP credentials or API integrations in a controlled way and test before production rollout.

Move Traffic Gradually

For substantial volume, a staged migration can help avoid abrupt changes in sending patterns.

Monitor Closely

Watch bounces, complaints, delivery activity and application errors during and after the migration.

Common Use Cases

Before Migration

Inventory domains, applications, credentials, volume and recipient suppression data.

During Migration

Authenticate, test and move traffic in controlled stages.

After Migration

Monitor delivery signals and remove old credentials only after the new workflow is stable.

Deliverability matters: SMTP infrastructure can support a strong sending program, but inbox placement cannot be guaranteed. Authentication, sender reputation, recipient consent, list quality, content, engagement and receiving-provider decisions also affect delivery.
