You’ll see the “Error: Too Many Recipients” message (sometimes known as a 452 error) if you attempt to send more than 250 emails within one hour, or if you attempt to send an email to more than 250 recipients at a time within one hour.
To avoid this problem, either break your recipients list up into chunks of fewer than 250 email addresses, then send one of those chunks each hour.
If you’re regularly sending emails to a long list of people, one simple way to do so is to use the Mailing List feature in My cPanel. You’ll find it in the Email section.
Create an email list for the first 250 recipients, one for the next batch, and so forth until you have enough mailing lists to cover your needs. Then email the first batch one hour, the second batch the next hour, and so on until you’ve sent all emails.
If you plan on regularly sending emails to email lists of more than 250 participants, consider signing up for an email service such as MailChimp, Aweber, GetResponse, or Constant Contact to avoid such limitations. Another great option is to purchase our VPS service for greater flexibility and control.
