Is there a daily email limit?

When buying the premium version the add-on does not limit how many emails a day you can send. However if you send hundreds of emails all in one go, Gmail might throw an error on you. This is Gmail's way of trying to discourage spamming. Therefore the following workaround are suggested:

  • Use tracking so you know which emails have been sent before the error is thrown at you. This way on the next merge you can continue sending emails from where you left.
  • Use scheduling to you spread the emails across time rather than all at one go.
