Why is Email List Hygiene So Important

If you want your emails to be delivered to the right inbox, having a clean list is must. For getting successful results from your email marketing strategy, maintaining a list of fresh and updated contacts that blends well with your campaigns is indeed crucial.

Facts to be Known

Bounce rate of 3-5 percent is an alert that your email list needs to be cleaned.

As more than 20 percent of email registrations contain typos, syntax and other errors, sending emails to an old list with high bouncing rate can set off an ISP’s spam alert.

Remember to re-engage your invalid email customers before removing them from the list to win back their interest in your brand.

Frequent cleaning needs to be done to maintain the quality and responsiveness of the list.

On an average, email marketers have seen 94% ROI from targeted emails when delivered to the right inbox.
