Suppression Lists

We first send your email through your suppression lists, which are specific to each account. There is also the option to send your email through the Global Suppression List, which is a database of all hard bounces and ISP complainers across all OpenMoves user accounts.


The ISPs then check the IPs sending the email for authentication, which is a means of validating that who you say you are, is really who you are. We can achieve even better delivery by registering and authenticating a a custom FROM address for you.


The next challenge your email faces is the sender reputation, which is the quality of the IP addresses that you are sending from.

Don’t worry, we spend every day monitoring our IP reputation and our clients to ensure stellar ratings. We can also provide warmed IP addresses for sending or send from pools of IPs made up of similar clients based on behavior.

We constantly clean/filter data through hard bounces, unsubscribes and feedback loops to maintain and improve your reputation and delivery.

Content Filtering

Once your email has passed the authentication and reputation checks, it is then moved into the recipient’s content filtering, where the content and construction of your email is checked to see it qualifies for the inbox.

The OM3 Inbox Preview spam tool checks spam words and email structure and will give you a good idea whether your email will pass the content filtering before you send your email.

Custom  URL, SPF and Domain keys

By default your emails will be sent from a generic domain called To maximize inbox deliverability and protect your main domain reputation we recommend sending your emails from a custom from address that’s dedicated to email marketing. The purpose is to let the ISPs know that you are who you say you are and that your email is not a result of phishing. For a small onetime fee up we’ll register and authenticate your chosen custom domain (i.e. and set up SPF records and domain keys to maximize deliverability. This is part of a recent industry wide initiative called DMARC (Domain-based Message Authentication, Reporting & Conformance) that was created to reduce the amount of phishing emails and emails with fake sending addresses.
