How to evaluate email infrastructure

Email infrastructure must balance sending reliability, authentication, observability, and the product workflows it supports.

1. 1

   Deliverability controls

   Review authentication, suppression, bounce handling, monitoring, and the support available during delivery issues.

2. 2

   Technical fit

   Check API, SMTP, event, template, and integration requirements against your application or sales stack.

3. 3

   Operational ownership

   Define who monitors reputation, handles failures, and maintains customer communication preferences.

Pricing
