You should also know when to stop emailing them.<p>I have received over twenty emails from Facebook, asking me if I know Tom Levesque, and to SEND him a friend request. Over and over, and over again. No, I don't know a Tom Levesque. I don't need to be asked the same question repeatedly.
I also thought those fb emails, and even more so the linkedin ones where people endorse you to be very effective. So I personally hated and admired them at the same time.<p>The problem for me is that those tactics don't seem to translate so well outside of the social-network environment. When you have customers who use your products, and there's no personal interaction between customers, then what can you use that's as effective to bring customers back to use your product?<p>Features is perhaps the only thing, but it's not even remotely as effective in my opinion. And features can be a double-edged sword as they are quite often not really important to the customer.
Persistent emails does not win me over. In fact when a reputed company / product I may have once tried sends me irrelevant emails, I just use the spam button.<p>Don't call (email) me, I'll call you (visit your website when i need to).
I've never used Facebook, but I'm flooded with messages from Twitter and LinkedIn which are identical to these.<p>Personally, I'd be much more likely to read and consider re-signing by way of less frequent messages which suggest <i>how</i> the product has been improved and <i>why</i> I might want to come back.<p>Incessant "FOMO" pressure just trains me to ignore that pattern.
Well, I can hardly see a chance of using this in a service thats not a social Network.<p>For every other kind of service/app, I would send a reminder once in a while and/or showing the users what has changed on the service since their last visit.<p>Or much more crazy: ASK them why they are not coming back. If they are unhappy with your service. I think you might be suprised about how many valuable answers you will get.
Thanks for sharing Alex! Are there any other companies you think are worth looking at in terms of email marketing?<p>I'm personally a fan of how well designed Twitter's re-engagement emails are.
