According to MarketingSherpa, the average email list depreciates by 25% every year. To improve email deliverability you need to scrub your email list to reduce duplicate, invalid, dead, and bogus emails. Like a good spring and fall cleaning, scrub your list every six months to keep your email list healthy.
Follow these 9 tips for keeping a healthy email list:
Tip #1 – Don’t purchase lists. Don’t purchase lists from third parties. Sure, it has short term benefits but it negatively affects your delivery and sender reputation in the long-run. Recipients are much more likely to hit the “spam” button when they receive email from an unknown source. Very few good leads or good results come from purchased lists.
Tip #2 – Remove alias emails. Alias addresses are things like contact@company.com or support@company.com. Many ESPs are not successful at delivering to these types of addresses because not all of the email addresses associated with the alias has opted in to receive communication from you.
Tip #3 – Keep your suppression list. List suppression means that subscribers have been added to the list because they have been unsubscribed, or emails sent to the email address have bounced. With these inactive subscribers flagged in your account as “suppressed,” it prevents any further emails being sent to them.
