Even if your emails offer valuable content, there will be some users who want to opt out. This could be due to reasons like receiving too many emails or a shift in their interests where your information is no longer relevant to them. In such cases, it's crucial not to retain subscribers against their wishes.

To respect your users' preferences, ensure that the option to unsubscribe is prominently displayed. Make the process of unsubscribing clear and straightforward. Demonstrating this level of transparency leaves a positive impression, and there's a chance that users may return in the future. Conversely, attempting to deceive them into staying can lead to frustration and potentially harm your relationship with them.
