Emails triggered by milestones, like anniversaries and birthdays, are fun to get -- who doesn't like to celebrate a special occasion? The beauty of anniversary emails, in particular, is that they don't require subscribers to input any extra data, and they can work for a variety of senders. Plus, the timeframe can be modified based on the business model.


At worst, you might think I’m a bit weird for caring so much about sound quality. Or you might think I’m really weird if you knew that my loudspeakers are computer calibrated to my room. Or you might question my priorities if you knew I set up my office, so that my desk is nearly in the middle of it… mainly to be able to enjoy music better. But we’re all weird in some ways (and I’ll let you think this is the weirdest thing about me).

Did you know there are organizations dedicated to combating email spam? Thank goodness, right? They set up a little thing called a honeypot, which is a planted email address that, when harvested and emailed, identifies the sender as a spammer. Similarly, things called spam traps can be created to identify spammy activity; they're set up when an email address yields a hard bounce because it's old or no longer valid, but still receives consistent traffic. Fishy, eh?

Sample review: Optinmonster “has various forms you can embed on your site to help with email conversion but one of the most interesting ones is the popup. You can set the popup only to appear on ‘exit intent’.  This means that your website visitor can browse all they want and when they are about to exit the website you can have a popup appearing tempting the visitor to leave their email address.” — RazorSocial (World)
Ask for the right information upfront: Great personalization starts way before you hit the ‘send’ button. It all starts with your sign up form. Without data such as name, company and location, you will be very limited with your personalized communication. Remember to only ask for the information you need, rather than the information you want. This is one of the ways that GDPR has impacted marketing teams.
