If you want your users to appreciate your brand communications, you need to allow them to conveniently manage their subscriptions. It includes unsubscribing from your emails as well.
Try to incorporate a simple ‘unsubscribe’ or ‘manage subscription’ option in the footer of your email. You can also give them the option of setting their email preferences and deciding which emails to receive and how often.
If your users constantly get unwanted emails, it gets frustrating for them. It generates a negative feeling towards your brand if they find it difficult to unsubscribe. And, if they mark your email as spam or junk, your emails will more likely be marked as spam in others’ inboxes.
Remember that it is not necessary to give your users to only opt-out of receiving emails. You can also allow them to manage their subscription. It will help you still keep your customers, and they will be happy to receive your emails on their terms.
That is the reason to include a double opt-in option while creating the list so that you know the recipients are completely happy getting emails from you.
