FAQ Glossary

Sender Score
A unit to measure the reputation of the sender. A higher sender score will lead to higher deliverability.
Shared IP
Unlike dedicated IP, a shared IP is an IP address used for multiple sites. The IP address of a website is used for multiple sites on the server, which is why the bad actions of one site can deteriorate the IP reputation of all the other websites sharing that IP on the server.
Single Opt-in
When only one action is to be taken in order to opt-in the list of subscribers of a particular list. E.g. – When you ask them to submit their email address for future updates and no email verification is needed. Double opt-in is more advisable as people might give fake email addresses which will hurt your domain sender score in future.
Soft bounce
A soft bounce, on the other hand, is an email that failed to deliver because of temporary reasons. These soft bounces will occur when a file is too big or a recipient’s inbox is full. These soft bounces aren’t nearly as problematic as hard bounces. And, usually, an ESP will try and deliver these soft bounces again.
Spam Cop
Spam cop is a service that allows spam or unsolicited email receiver to report that IP address to “SpamCop Blocking List” or “SpamCop Blacklist” (SCBL). Once a domain gets in this list, it is really tough to gain its reputation back.
Spam Filters
The smart filters that automatically traces emails that are spammy or unsolicited and throws them into the spam folder are called spam filters. You need to be sure on how to avoid spam filters in order to get the most out of your emails.
The Sender Policy Framework is an email-authentication technique used to avoid spammers from sending emails on behalf of a domain. Once you authentic your domain, the filters will know that your emails are not spammy and sent to serve a purpose, not fraudulent activities.
The people who have signed up to receive your email messages.
Subscriber Value
How much a subscriber is worth to you financially.
Suppression File
A list of email addresses that should not be mailed to. Some companies maintain a global suppression file. Even marketers in separate divisions may not mail to a global suppression file.
