I like other publishers have had our share of bouncing email addresses. Hotmail and Zwallet accounts are not only culprits are many claim. Email addresses are of all makes and sizes.
I have had subscribers that have been on my list for eons it seems and suddenly their email bounces two or three times. What is cause of this scenerio? Perhaps their ISP is not working or they are away and forgot to put mail on hold or even forgot to pay their bill. Even forgetting to check inbox may cause a email to bounce.
Patience is a virtue for those loyal friends. Keeping a log of bouncing emails may solve problem. Just recording dates and times and what email they coincide with, may just keep you from deleting a loyal subscriber with a slight problem.It probably is just that!
Solo Ads have a way of subscribers driving subscribers away, as do Classified editions. But subscriber fails to see that these emails are a part of publishing and they had their ad listed in those classifieds once too. Solo ads are "paid" advertising and deserve their place in limelight as well.
But on flip side there are those fake email addresses that really get under your skin and trying to track them literally wears you out. This is a sneaky attempt to subscribe with a free ad, over and over again, until you happen to get caught..maybe!
I immediately reply to my new subscribers either personally or through my host, Topica. Topica does a great job handling bouncing emails, either they are a soft bounce[temporary] or a hard bounce[cannot be delivered at all.] I always reenable a soft bounce, keeping track of course and immediately delete hard bounces. I don't need harassment, yet I give those soft bounces another try. If I send a personal reply and it bounces, forget it, deleted, ad and all. No shame! Get a "Real Email Address or do not subscribe." Case closed!
