You built your app with Bubble because you wanted complex web applications without code limits. The platform handles ambitious projects that other no-code tools cannot. Now you need email that matches Bubble's capability for sophisticated workflows.

Bubble's plugin ecosystem includes email tools, but most lack marketing automation. Basic send-email plugins handle transactional needs, but for sequences, segmentation, and behavioral triggers, you need dedicated platforms. Your email tool should work with Bubble workflows to create sophisticated automation.

This guide covers 12 email marketing tools that integrate with Bubble applications. I focused on platforms with plugins or API integrations that work within Bubble workflows. If you are using a different no-code tool, check out our guides for Glide, Adalo, or FlutterFlow.

1. Sequenzy

Price: Free (100 subscribers) / $49/mo at 10,000 subscribers. Transactional emails included at no extra cost.

Bubble's plugin ecosystem includes basic email, but most lack marketing automation. Sequenzy's API can be called from Bubble workflows for both transactional and sequence emails. One API call adds a user to a welcome sequence. Another triggers a re-engagement campaign.

The visual sequence builder creates sophisticated onboarding, trial conversion, and churn prevention flows. AI generates complete campaigns from descriptions. At $49/mo for 10k subscribers, it is 67% cheaper than ActiveCampaign and 94% cheaper than HubSpot.

Revenue attribution connects emails to actual conversions. Stripe OAuth syncs payment data for MRR-based segments.

Integrate via Bubble's API Connector. Define Sequenzy endpoints, then call them from workflows.
