The need to warm up a mail server is state of the art today – you can’t send large amounts of WordPress email unprepared if you don’t want to be punished as a spammer.
One possibility is that you generally limit the amount of email your server sends out. But this has the great disadvantage that you are hardly able to act for weeks.
Campation MXWarmUp™ takes a more dedicated way and warms up individually the particular channel between your sender email address, your mail server and a recipient server (e.g. Gmail) so that a trusting relationship can develop.
Or better said: not with a single recipient server but so called MXClusters which are server clusters consisting of many servers and many IPs that occur with large email providers such as Gmail, Outlook or Yahoo. Such data centers are not only used for email domains like “@gmail.com”, “@yahoo.com” etc., but millions domains more that are hosted there.
What is essential, however, is that these gigantic email server structures entirely monitor all incoming emails and thus easily can determine when a sender (like your WordPress site) unexpectedly sends large bulk quantities to many email domains hosted there. This of course immediately raises the suspicion of spam.
During warm up Campation PostOffice controls the email quantity sent to any MXCluster rather than to a single server.
The Campation MXWarmUp technology recognizes such server clusters and treats them as one receiving mail server while warming up any of them individually. The special thing about it is: Campation PostOffice™ behaves individually towards each MXCluster of recipient servers!
Within the parameters you set, during the “pre-warm-up” all emails are sent “like a human” for a few days, not only in terms of speed, but also with simulation of an email client such as Microsoft Outlook. After that phase, the allowed amount of emails to a specific MXCluster increases daily until the target volume is reached.
A MXChannel is the combination of your sender address, your outgoing mail server and the receiving MXCluster. If you – for example – are using 3 different sender addresses and 2 different outgoing mail servers then you will have 6 different MXChannels e.g. to the Gmail data center. When sending emails to “@gmail.com” and “@company-a.com” and “@company-b.com” (which all are hosted in the Gmail MXCluster) all those emails will be routed through the 6 MXChannels that exist into direction Gmail – and which are warmed up individually.
You can observe open and click rates, spam rejects and unsubscribes for each MXChannel to recognize when something is going wrong.
The warm-up process itself runs continuously in the background: anytime you mail to a new recipient address whose MXCluster is not yet known, the same warm-up process will start for this server as other servers already have gone through. Means: Campation PostOffice continously is warming up new recipient MXClusters.
The Campation MXWarmUp process is controlled by a function that calculates the maximum daily number of emails per MXChannel depending on the progress of the individual process.
For example, if you send 100,000 newsletters in one go, Campation PostOffice during warm-up distributes them over a longer period of time by calculating an embargo for each single email. Small MXClusters, such as a corporate mail server, to which you only send a few emails, receive all emails very quickly – large MXClusters, such as Gmail, take correspondingly longer to drain during the warm-up.
Despite a warm-up phase, your emails flow off much faster than without Campation PostOffice’s MXWarmUp technology (limiting the whole output of your server) – while at the same time building up trust and reputation for the direct route to the INBOX of your subscribers!
Once the WarmUp phase is complete for a MXcluster, Campation MailThrottle™ can permanently protect that sending channel: You may configure a maximum number of emails per minute that may be sent via a MXChannel, with the result that 10,000 emails to Gmail addresses may be generated in one fell swoop, but always will flow over a longer period of time in the background.
