A few months ago, my inbox was filled with emails from a health specialist. I didn't remember signing up for random diet plans, so why was I getting constant emails?
I was ready to fire off a complaint, but I checked my inbox first. There it was, an opt-in email I'd actually subscribed to. The specialist hadn't been consistent with their communication, so it completely slipped my mind.

This is exactly why opt-in emails are crucial. They save you from annoyed subscribers and maintain a clean, respectful email marketing strategy. Opt-in emails ensure that people remember to give you permission to send them content. Without them, you risk becoming just another forgotten sender-or worse, marked as spam.
