High volumes of email can cause blacklisting[/caption]
Like all email service providers, our team needs to be careful to ensure that our mail servers do not get listed on spam blacklists.
Once a mail server is listed on a spam blacklist, it means that the deliverability of the emails on that system will drop precipitously, meaning that email senders on that server will not be able to email many of their normal contacts.
For example, if our email server became blacklisted, our clients would have a hard time emailing their colleagues and friends. There are many reasons that a mail server can get listed on a spam blacklist, the most obvious reason being the actual sending of spam.
There are other reasons beyond the obvious that could cause us to be listed as well, including sending unusual volumes of email in a short period of time. For this reason, our team has put in some outgoing email guidelines, which are designed to minimize the risk of our servers being blacklisted due to suspicious behaviour.
Essentially, our guidelines restrict the number of TO, CC or BCC contacts you can have on any one email. This means that if, for example, you wanted to send out an email to 1,000 of your clients, the best way to deliver these would be to send 1 email to each of the 1,000 clients, instead of trying to send 1 email with 1,000 BCC addresses on it. Our entire outgoing email restrictions are laid out below.
Max Recipients per Message: 200
Max Message Size: 20MB
Max Messages per Hour: 500
Max Outgoing Bandwidth per Hour: 100MB
