Integration
MailPilotX and Excel online: lists from OneDrive
An Excel table (email, first name, locale) can become a MailPilotX list: CSV import or Zapier « new Excel row ».
How to connect
OneDrive / Excel Online + Zapier, or .csv export then MailPilotX import. Dedupe and drop rows without consent first.
Honest limits
No official Excel OAuth app. In the product, MailPilotX Sync gives you a secret webhook URL (Pro / Business): the tool POSTs JSON, the contact lands in your list. CSV and the REST API still work.
