QUESTIONS

Which newsletter platforms does ParseHook support?

Any platform that sends signup notification emails: ConvertKit, Mailchimp, Beehiiv, Substack, Ghost, MailerLite, and custom signup forms.

Can I use this to sync subscribers to my CRM?

Yes. ParseHook fires subscriber data to your webhook. Your handler pushes the data to HubSpot, Pipedrive, or any CRM with an API. Real-time sync without Zapier.

What if I get unsubscribe notifications too?

ParseHook parses those as well. The type field will indicate signup vs unsubscribe. Handle each type differently in your webhook logic.

How quickly does subscriber data reach my database?

Within 5 seconds from signup notification email to webhook delivery. Your CRM or database is updated in real time without any manual step.

Can ParseHook extract subscriber tags from ConvertKit or Mailchimp?

Yes. Tags included in the notification email body are extracted as a structured array in the JSON output alongside name, email, and source.

What if my signup form has custom fields beyond name and email?

ParseHook extracts all fields present in the notification email including custom fields, regardless of the form or platform structure.

Can I route signups from different newsletters to different webhooks?

Yes. Create a separate ParseHook inbox per newsletter or platform. Each inbox has its own webhook destination so routing is fully independent.

Does ParseHook work with self-hosted newsletter tools like Ghost?

Yes. Any tool that sends email notifications for new subscribers is supported. Ghost, Buttondown, and custom self-hosted solutions all work the same way.
