Submit a tool
How we decide which email and lifecycle platforms belong in the directory, and how vendors or practitioners can suggest additions.
Inclusion policy
Growth Marketing Index lists platforms that help teams run email marketing, lifecycle automation, or developer-owned sending. We include incumbents and newer AI-native tools when we can verify product claims against documentation and documentation-based analysis.
- Public product with a marketing or developer-facing website
- Email or multi-channel lifecycle capability, not SMS-only tools
- Pricing or packaging information we can cite with a date
- No pay-to-rank placement: sponsorship does not change scores
Submission process
- Email Brew documentation with the product name, URL, and category fit.
- Share documentation links for pricing, API or MCP surfaces, and integrations you want listed on the fact sheet.
- Allow two to four weeks for editorial review. We may decline tools we cannot verify or that fall outside lifecycle email.
Corrections and updates
Vendors can request fact sheet corrections anytime. We date every last-verified field and publish methodology on our editorial standards page.
Publisher disclosure
This publication is operated by GetBrew, the maker of Brew. Recommendations are documentation-based editorial judgments. We cite vendor sources and describe the tradeoffs of alternative tools.
