There is a 200 outgoing email hourly limit per domain. If you send over this amount in an hour, most of the e-mails will bounce back with an undeliverable error. If this occurs, it will then take some time for your account to be able to send again so we recommend waiting at least 1 hour after this issue occurs to begin sending email again.
Many of our servers have a limit of 30 POP3/IMAP checks per hour per IP address. If you go over this you’re likely to get a wrong password error message or an error stating “login incorrect”. If this occurs, please wait an hour and it will automatically unblock you. To prevent this from happening again, please make sure to disable auto checking or at least set it to something higher such as once every 10 minutes.
Any mailing list larger than 900 addresses will require a dedicated hosting solution from us. Note: Dividing one large list into smaller lists to get below this limit is not allowed.
Any unsolicited e-mail being sent will result in suspension or termination of the offending account. We take a zero-tolerance stance against sending of unsolicited e-mail and other forms of spam.
Any mailing list MUST comply with all guidelines set forth by the United States government. These can be found at:
No direct SMTP mailers are allowed. An example of this would be a Darkmailer or The Bat!. Any mail should be sent through the local mail server/MTA for further delivery by the server and not done directly by scripts.
2) Mailing List
Any time you’re sending a message no matter how large your e-mail list is you must throttle it. We recommend you throttle it to at the very least sending one email every 10 seconds. If the mailing list software you’re using does not allow you to throttle you must switch to an application or script that will or switch to an email marketing service, i.e. Mailerlite or MailChimp.
