Every email provider sets limits on how many emails you can send within a certain time frame, and as an email client, Polymail must follow these rules too. Your sending limits can vary depending on factors like how long you’ve had your account and whether your account has been flagged for spam activity.

If you exceed these limits, your email provider may temporarily restrict your account. This can lead to emails not being delivered, interruptions in email syncing, and reduced functionality. Unfortunately, this issue cannot be fixed on our end—you’ll need to wait until your sending quota resets.

Here are some general guidelines for daily sending limits:

  • Gmail: 500 emails per day
  • Google Workspace: 2,000 emails per day (500 for new or trial accounts)
  • Outlook & Office 365: Limits vary depending on domain size and account age
  • Office 365 Business: Up to 3,600 emails per day
  • IMAP accounts: Check your provider’s documentation or contact support for specific limits

If you run into sending restrictions, monitoring these limits and pacing your email activity can help prevent interruptions.
