Overview:
GMass is a unique service in the email marketing space because it's built on top of Gmail. That means, unlike a traditional email marketing service like MailChimp, GMass doesn't have any email sending servers or sending IP addresses. All emails are sent from our users' Gmail accounts and therefore through Gmail's IP addresses. The benefit of this is that your emails are sent through the world's highest deliverability servers, since virtually nobody blocks Gmail's IP addresses.
This, however, doesn't mean that our users are immune to getting blocked. If the content of your email is deemed spammy, then Gmail itself may block your account, or your recipients' email servers may block your emails.
GMass doesn't monitor its users:
GMass intentionally doesn't monitor its users. Meaning, accounts don't need to be approved before you can start using GMass to send an email marketing campaign. Why don't we police our users? Because Google does most of the policing for us. If you use GMass to send spam, it's likely that Google's automated systems will be triggered and your Gmail account will be terminated. It's unlikely that we'd be able to develop a better algorithm than Google already has in place for detecting and terminating spammers.
However, even Google's spam detection mechanisms might not be fast enough in some cases. Lots of spammers succeed in using GMass to send some spam out before Google notices and terminates the associated Gmail account.
Your emails could be blocked:
Because of that, it's possible for your legitimate emails to become associated with a spammer's emails and for you to also get blocked. How are your emails connected to the spammer's emails? If you're using GMass's open tracking, click tracking, or unsubscribe features, then a "tracking domain" is inserted into your email to allow those features to work. If you're using open tracking, then an invisible pixel is placed at the bottom of your emails, and the domain referenced is the tracking domain. If you're click tracking your links, the links are altered so that the GMass server is hit first to record the click, and that's done by way of the tracking domain. Unless you've set up your own custom tracking domain, GMass uses default system tracking domains across accounts. Typical default tracking domains look like gmss1.com or gmss1.xyz. They are variations of the word "gmass" with the "a" removed, using various Top Level Domain (TLD) extensions from .xyz to .net to .com.
Some spam filters catalog domains that are commonly found in spammy messages, so if your emails contain the same tracking domain as the spammer's emails, then your emails can also get blocked.

The simple one-step solution:
The solution is a simple one. Your accounts should use a tracking domain that is specific to just your email campaigns. You can easily set up a branded tracking domain for your GMass accounts that is based on your OWN domain name, or if you don't know how to manage DNS records, we can provide a dedicated tracking domain for your accounts. Regardless of whether you have a Gmail account or a Google Apps account, you can take advantage of this capability.
That is the single most important step you can take to maximize your deliverability and avoid blocking issues.
