How do unsubscribes impact email deliverability and should I automatically correct email address typos?

Email marketer from Sendinblue explains that while unsubscribes are a normal part of email marketing, a sudden spike in unsubscribes can raise red flags with ISPs. It's crucial to monitor your unsubscribe rate and investigate any significant increases to identify and address potential issues with your email content or targeting.

Email marketer from Litmus shares that while unsubscribes themselves don't directly harm deliverability like spam complaints, they are an indicator of engagement (or lack thereof). High unsubscribe rates suggest a mismatch between your emails and subscriber expectations, which can indirectly impact your reputation and future deliverability.

Expert from Email Geeks shares that not just Google supports list-unsubscribe headers, but also Microsoft, Apple, 1&1, and Yahoo.

Expert from Spam Resource explains that while it may be tempting to correct typos in email addresses, it's fraught with danger.

Expert from Word to the Wise explains that list-unsubscribe options are not equally effective across different providers. Senders need to implement both one-click unsubscribe and a confirmation page to adhere to industry best practices. Providing only one option will limit subscriber opt-out and potentially result in negative reputation.

Expert from Email Geeks explains that unsubscribes generally appear as regular clicks, except at Google. At Google, if someone marks a message as spam and the sender has a good reputation, Google may ask if they want to unsubscribe. If they choose to unsubscribe via the List-Unsubscribe header, it can negatively impact reputation as it is treated like a spam complaint.

Expert from Email Geeks states to never fix a bad email address because you cannot infer the correct address from a typo. Instead, focus on fixing the process that allows bad addresses into the system, such as asking for address confirmation or using "did you mean" features.
