To prevent our new infrastructure from becoming blacklisted by other email providers, which effects all other clients, unlike the old system, our new hosting environment does not tolerate sending emails in bulk.
Why is this happening now?
It has always been against our terms of service to send large batches of emails. However, on the old mail servers, we had nothing in place to prevent it. This lead some users to think this was an inclusive part of our email service because we did not pursue or take action to stop the behavior, that is, unless it was brought to our attention.
We've strategically configured our new hosting environment so that it does not allow this behavior, and for good reason, it's in their own and others best interest. Subsequently, for the users this has a negative impact on, you will need to find ways to work around the limitations or begin using the proper platform for performing campaign level emails.
How does this new max-emails-per-hour limit work?
It's important to note that the limit is only per hour. If you wish to continue sending mail in bulk, the messages will be sent out, but just in batches, for each hour your over the limit.
Example: If you send 600 emails, starting at 1pm, 150 emails will go out without issue, the remaining get queued until your under the limit again. Therefore at 2 pm, another 150 will go out; at 3 pm, another 150; and this will continue until you're under the 150 per hour limit and the queue is empty.
It's important to remember that if you continue to go this route of sending emails in bulk all at once, it effect all email accounts on the particular domain name during the time it's being sent, until all the messages are delivered.
Example: If email@example.com sends 600 messages at 1pm, then firstname.lastname@example.org sends a single email at 2pm, Jon Doe's message will not be delivered until ~3 pm, because 600/150 = 4 hours. The only exception is if you send the mass-mail in smaller burst; which is mentioned below, keep reading for more details.
How can I avoid being limited?
- Send a request to have the limit raised, and provide a reason and the number of emails per hour you wish to be capable of. Under certain circumstances, we may individually increase your limit.
- Use your mail client software to limit the amount it sends; aka Batching or Mail Merging.
- If #1 and #2 aren't possible, then you'll need to begin following industry standards and use an appropriate platform/service for sending mass emails. Ask us about our very own, called Eblast http://eblast111.com/, or another choose a third party company such as MailChimp or Emma that will best suit your unique needs.
