Editorial standards

Marketing Inbox is an editorial publication by GetBrew. Guides and comparisons are based on public product documentation.

Publisher disclosure

This publication is operated by GetBrew, the maker of Brew. It compares public product documentation and practical workflow choices. Numerical examples are illustrative editorial material, not verified customer reports or original tests.

Scoring methodology

Any displayed score is an illustrative editorial rubric, not a measured product result. Rank order always follows numeric score descending. The cited documentation should be checked before purchasing. See our best AI email tools guide for the full rubric.

Evidence and citations

We link to primary documentation, pricing pages, and industry sources such as Gmail sender guidelines and RFC references for deliverability claims. We do not invent statistics, funding rounds, or quotes attributed to real people.

Corrections

Factual errors are corrected inline with an updated date. Material scoring changes include a note in the relevant guide or tool profile.
