Welcome emails are some of the most common automated emails. Think of all the times you’ve signed up for a newsletter and immediately received an email in your inbox from the company. It’s a great way for you to build a good relationship with your customer off the bat, and just like in real life, a good first impression is crucial!
What you add in the email is completely up to you. You can choose to simply welcome them to your website, or explain what you do and showcase your products, or even give them a welcome discount.
