When you set up an email server in Method:CRM, Method:CRM sends emails out on your behalf using your email provider.
In order to prevent potential spamming, most email providers limit the number of emails you can send in a 24 hour period, and how quickly you can send out emails back to back.
Learn more about the email sending limitations for the following email providers:
