The Sender Reputation is an individual metric at each email provider and is not something that they publish or give access to. You can gauge your sender reputation by looking at things like open rates or bounces, but there is no way to get access to it directly. The better your sender rate, the more likely you are to end up in an inbox rather than a folder or the trash can.
Consider using conditional formatting in excel to look for typos like ‘gmal.com’ or ‘yahooo.com’, as well as bogus email addresses like test@test.com when you purchase email lists. Additionally, consider a service like Debounce or Zerobounce that can help remove spam trap addresses that may have snuck onto your list. Removing these before you import your list and begin your campaign can make sure you’re sending to the people you want to reach and help keep your sender reputation up.
It’s important to get affirmative consent from users on lists you purchase before you begin to send them high volumes of traffic. Every time someone deletes your email unread or worse, reports it as spam, your reputation suffers. By checking to make sure a contact wants your content, you can avoid someone marking all your mail as unwanted. This is as simple as adding a field on the Contact object called opted in, and sending a welcome email to new list members with a Form Assembly form that checks that box if a user consents to mail. Then, filter your report on that value. This way you’re only sending repeat messages to people who want what you’re offering.
As an email best practice, we do not recommend adding attachments to mass emails. Attachments greatly increase the chance of being marked as spam, as well as decrease the chance of a recipient opening the email message. As a result, we do not offer this functionality in our product.
Instead, you can upload your documents to your server or other services such as Dropbox and use links to the files within your email. This also allows you to track who downloads the file with email tracking on.
If you are sending 100 messages a day six days a week, and 10k on the seventh beproviders will generally consider that spammy behavior. Consider breaking your reports up to distribute your send volume throughout the week or month. The more consistent your volume on a day to day basis, the better your sender reputation will be.
The longer an email sits in an inbox without being opened, the more likely your sender reputation is to be dinged, even if it is eventually opened and interacted with. As such, try to send as much mail as you can during business hours in a recipient’s local time zone. Consider breaking up your reports based on time zones, which can be derived from state or country info, so that you’re not sending mail to recipients in the middle of the night.
One of the best things you can do is send more mail to people who are highly engaged, and less (or no) mail to those who aren’t actively engaged with your content. Right now you can do that based on who has viewed or clicked an email based on EBM data, but that’s challenging due to the small timeframe users have access to due to storage needs.
