Asking subscribers to whitelist your email can actually make a big difference. Whitelisting means they add your email address to their contacts or safe list so your messages don't go to the spam folder. It is a simple request that helps your emails reach more inboxes. You can include a short line about it in your welcome email, explaining why it matters in clear terms. For example, you can say, "Add us to your contacts so you don't miss updates or offers." Just make sure it sounds polite and not pushy. Have you ever added a brand to your contacts list to keep getting their messages?
