Brew takes brand context and a prompt to create an email, then supports visual edits and agent revisions. It also imports existing designs and remixes public examples. Compare the output using your actual logo, type, links, and required footer.
Loops provides an email editor and templates, along with agent tools. Its MCP server can work with campaigns and workflows. Decide based on the edits your team makes repeatedly, rather than the presence of an AI label.
Both tools can respond to product events. Map the exact event name, recipient, properties, and duplicate-delivery behavior before publishing a flow. Marketing and transactional messages also need the appropriate consent and sender configuration.
In a Brew event-triggered automation, payload fields retain their original values after a wait. A contact.<field> condition reads the current Brew contact when that node runs. Keep the field synced, and use an application-side check when eligibility depends on external billing or product state. Review the corresponding Loops behavior and test conversion during a delay rather than assuming identical semantics.
Recreate one existing email, send it to test inboxes, and review mobile rendering, links, personalization, and unsubscribe behavior. Then test an event-driven sequence with an activated, unactivated, and unsubscribed contact.
Keep the original system responsible for live sends until the replacement passes those checks. Migration also includes contact consent, suppression records, domain setup, and any active workflow runs; copying HTML alone does not transfer those records.
Free tier available, paid plans from $99/mo (Growth) and $249/mo (Pro)
AI credit usage and email sending allowances are separate. Check current limits on the pricing page.
Loops allows unlimited stored contacts on its free plan, with 4,000 sends per rolling 30 days to the 1,000 newest contacts. Paid plans are priced by subscribed contacts and include unlimited sends; tiers are on its pricing page.
Choose Brew if generating and revising branded email is the bottleneck. Choose Loops if its editor and product-event workflows already fit your team. Compare one campaign and one state-dependent lifecycle flow in both tools before migrating.
Brew publishes this comparison. Brew Team reviewed the linked first-party documentation on 2026-09-29. This is a documentation review, not a claim of hands-on testing of every product. Pricing and plan limits can change.
