 Make Use of Double Opt-in System

Once a user subscribes to receive email communication from your brand, send them a reconfirmation email to be double sure about their subscription. While many may sign up for the first time, but only those who are serious will double confirm their subscription and prove that they are interested in receiving content from your brand. Implementing a double opt-in strategy will ensure no fake emails enter your database and keep you list clean.

Remove No-action Subscribers

There is no use of keeping no-active subscribers on your list as they never open your emails. Sending them emails not only wastes time and money but also puts your efforts into vain and screws up your overall email marketing metrics.

So, start with removing all those contacts who have not responded in the last 90 days to your email campaigns.

Request Your Contacts for Feedback

It is essential to determine if your contacts are loving your campaigns or email content or are not interested in what they have been receiving from your end. When you are trying a new campaign format or content, ask for customer feedback to know their opinion.

You can even request contacts to set how frequently they want to receive email communication from your brand or what topics they find interesting, etc. You may conduct polls as well for more in-depth insights on subscriber content preferences.

Take the feedback of contacts and build your email campaigns accordingly so suit their needs and interest with regards to emails. If contacts are still disengaged even after all these efforts, do not hesitate to remove them from the list.

Run Re-engagement Campaign

Sometimes, your subscribers’ low engagement may be due to the content you provide and not with the overall brand. That is why before you scrub your email list, once try to revive their interest to re-engage them.

Send them ‘we miss you’ emails as part of your re-engagement efforts. Such campaigns may comprise offering a gift or a discount coupon. But make sure amidst such offers, you must not avoid focusing on your content quality. Try to re-engage contacts through quality content, along with offering them freebies.

If, even after sending re-engagement emails requesting to reconnect, does not yield a response from subscribers, then email only critical events or product news to them. On the other hand, if they respond, ask them to keep your emails from the spam folder, which may be one reason for their disengagement.

Offer Easy Unsubscribe Option 

Make sure not to make the unsubscribing process difficult or time-consuming for contacts. It is not at all a right great idea to keep your unsubscribe link hidden from subscribers because if they do not find the unsubscribe option easily, they will end up marking you as spam. And if that happens, this will damage your reputation.

We know that offering an easy option for clients to leave may be a bit risky. But if your email content is engaging, then your contacts will not even look at the unsubscribe button.

While some may recommend getting your list clean yourself but professional expertise and assistance is what you must opt for to get the best results.
