I've always subscribed to my own email lists.
I do this to make sure the emails are sent out as they should. This is especially important when using any automation or behavioral emails.
Of all of the things that can break emails, automation is the top one for going unnoticed. The more of automation you use, the more you are "programming" your provider's email system and like any programming, you'll have bugs. Some will be caused by your automation, some will be the provider's fault.
Whatever the source, the bugs will end up hurting you and making your store look bad. Bugs will get your customers stuck, send them duplicate emails, cause them to miss out emails, send them the wrong content, etc. Combine that with SMS automation and you can see how much damage these bugs can cause.
Having yourself and your staff in your email lists are ways to detect some of those automation bugs. Some are going to even be bugs in the email provider's system.
You won't catch them all but the ones you do catch will help out your customers.
While it's easy to add yourself to your email administration directly, I recommend going through the routes a customer does. If you have an opt-in form, fill that out to get on the list. If you add customers when they order, place an order from your store.
It doesn't take much automation to attract and keep good customers either.
- a solid New Customer Welcome campaign,
- a way to add new customers,
- useful content, and
- a regular email schedule
That's all you need to get new customers on the track to become repeat customers. Pretty much every email provider has offered that ability for as long as I can recall (back to 2006ish when I got into email marketing). Some make it harder than it needs to be (not naming names).
Automation just adds complexity on top of that. Complexity that might or might not actually benefit your store more than the basic setup.
If you want to measure how your New Customer Welcome campaign performs, the Order Sequencing analysis in Repeat Customer Insights splits out customer's first order from their second, third, etc. It makes it clear how well new customers are coming back to buy again and how long it takes them.
Track down which customer cohorts perform the best
Different groups of people behave differently. Repeat Customer Insights creates cohort groups for you automatically to see how your customers change over time and spot new behavior trends.
