2. Is there a limit on how many emails a day I can send?

It depends what you use. By default, the add-on uses Gmail’s API to send emails which limits the number to 100 emails/day for gmail users. If you have G Suite its 1,500 email/day. Google sets these limits as you can read by clicking here.

To get around this problem there are two alternatives:
  • Schedule Emails.
  • Send email using an SMTP server. You can either use Gmail’s SMTP which allows you an additional 500 emails/day or use your own company’s SMTP server which basically is only limited by what your administrator allows. Set this up from your Google Doc by clicking the Add-ons->Mail Merge->SMTP Settings.
    • Gmail SMTP Settings

    • You can also use a 3rd Party SMTP Service such as
    • This service allows you to send 1000 email/day for free. However you have to batch them 25 emails/hour.
