Every email service provider has its own email sending limits. These limits are based on a daily, hourly or per-minute basis. Your email account may get blocked if you aren’t aware of your email provider’s limits.
As big marketing campaigns will have numerous emails with their follow-ups, so always know about the email sending limits before your email campaign goes into the risk of not getting delivered leading to account block.
Let’s go through various email service providers with their sending limits.
