Frequently asked questions
How does email tracking work?
Send a tracked email as usual. Mailbutler automatically tracks opens and link clicks with real-time notifications. Self-tracking prevention is enabled by default so opening your own sent emails won't affect results. Per-recipient tracking shows who opened it, when, location, and device.
Why might tracking not work?
Apple Mail Privacy Protection masks recipient IP addresses, preventing location and device visibility. Some recipients' servers strip tracking ability or prevent emails from large recipient lists.
What do I get with the free plan?
Free Starter tier includes basic open and link tracking, real-time notifications, email signatures and team sharing, but all sent emails include a visible Mailbutler watermark.
Which plan includes AI features?
The Smart plan ($11/month yearly) and higher include the AI Smart Assistant for email composition, summarization, and reply drafting. Full open history is also limited to Smart and above.
Can I integrate with my CRM?
Yes, the Smart plan enables CRM sync to HubSpot and Salesforce. The Business plan adds advanced features like custom tracking subdomains and IP exclusion.
