The marketer trying to improve delivery or sender reputation

ISPs closely monitor how subscribers interact with your email campaigns. And low engagement is a sure-fire way to get relegated to the promotions tab or worse. ListFit helps marketers find hidden cohorts of low and highly engaged subscribers, leading to more precise segmentation and better inboxing.

The marketer acquiring leads at point-of-sale

A customer signs up for an offer at the point of sale and enters an email address. ListFit determines if that address is real & active, plus returns an engagement score based on how often that subscriber interacts with marketing emails.

The retailer with an aging list is worried about losing engagement

A retailer wants to scrub their list for unengaged subscribers. ListFit scores each email address for activity level. Inactive emails can be quarantined until they show increased activity in the ListFit Global Data Pool.

The marketer using a contest to generate subscribers

Marketers using contests to grow lists can sign up a large volume of leads, but there is no way to evaluate how “good” a lead is. The ListFit engagement score is used to understand the quality of the address, making sending decisions easier.

The marketer trying to avoid spam traps for better delivery.

Spam trap seed emails can get added to a list fairly easily, threatening the sender’s reputation. ListFit scores and ranks each email addresses by their activity, automatically segmenting those addresses that could negatively effect deliverability.

The marketer trying to increase subscriber engagement

When trial and error campaign adjustments are slow to improve results, marketers turn to ListFit for insights and recommendations on when to send, how often, and to whom.
