Sendingflow
Connect Sendingflow, an email marketing automation platform, with Webflow to trigger automated email campaigns from form submissions on your site.
How to integrate Sendingflow with Webflow
The easiest way to set up your Sendingflow Webflow integration is by installing the Sendingflow app from the Webflow Apps marketplace. For teams that need more control. like CMS-driven newsletter triggers or engagement-based lead scoring, you can also build custom email workflows using Webflow's webhooks and CMS API.
Install the Sendingflow app from the Webflow Apps Marketplace to connect forms to automated email sequences. For advanced use cases like CMS-triggered newsletters or engagement tracking, build custom workflows using Webflow's webhooks and CMS API.
Use the Sendingflow app
Install from the Webflow Apps Marketplace. Map your Webflow forms to automated email sequences in the Sendingflow dashboard.
The app uses Webflow's native permissions system — no custom form action URLs required. Webflow's standard form functionality (submissions dashboard, notification emails) continues working normally.
Build custom email workflows with Webflow's APIs (developer)
For use cases beyond the marketplace app, build custom integrations using Webflow's REST API and webhooks. These require a developer and server-side middleware.
Since Sendingflow does not publish a public API, custom workflows send Webflow data to another email service with an HTTP API, or to your own backend.
Form submission emails
Use form_submission webhooks to trigger emails in real time. Your middleware receives form data, validates using the x-webflow-signature header, and forwards to your email service.
CMS-triggered newsletters
Listen for collection_item_created webhook events to notify subscribers when new content is added. Note: This fires on creation, not publication. Add a published status check if your team uses drafts.
Engagement tracking
Write email interaction data back to Webflow CMS. When your email service reports opens or clicks, update matching contact records via the CMS API for lead scoring.
What you can build
Integrate Sendingflow with Webflow to turn form submissions and site interactions into automated email workflows.
- SaaS onboarding sequence: A signup form triggers a welcome series with tutorials and trial-to-paid conversion prompts. Configure the full sequence in the Sendingflow dashboard using the marketplace app.
- Event registration pipeline: A registration form sends confirmation with calendar details, then delivers speaker highlights and logistics reminders on a timed schedule through the marketplace app's campaign sequencing.
- E-commerce post-purchase flow: An
ecomm_new_orderwebhook triggers confirmation emails, review requests, and repeat-purchase incentives on a timed schedule. This requires custom middleware. The marketplace app alone does not handle e-commerce order webhooks. - CMS-triggered newsletter: New blog posts added to a CMS collection trigger subscriber notifications through a
collection_item_createdwebhook and custom middleware that fetches subscriber data from a separate CMS collection.
Frequently asked questions
Install Sendingflow from the Webflow Apps marketplace, select your workspace and site, and authorize the requested permissions. After authorization, follow the in-app setup instructions to connect your Webflow forms to email campaigns.
Yes. Configure each form-to-campaign connection individually in the Sendingflow dashboard. A contact form can trigger a sales follow-up series while a newsletter form triggers a weekly digest, with sequences from 1 to 1,000 emails each. If you change your form structure in Webflow after setup, test both the form submission and the email trigger to confirm the workflow still works.
No. Sendingflow does not have integrations on Zapier, Make, n8n, IFTTT, or viaSocket, and does not publish a public API. The marketplace app works directly within Webflow's ecosystem. For automation workflows beyond form-to-campaign connections, use the Webflow Webhooks API to push data to a custom middleware endpoint.
Webflow enforces plan-based form submission limits. On paid site plans (Basic, CMS, Business, Enterprise), exceeding the limit results in overage charges rather than blocked submissions. On free or Starter plans, submissions are blocked after the lifetime limit is reached. Check your Webflow dashboard for current usage and limits.
