Welcome to Shopify Community. My name is Olivia and I'm part of the Shopify Team.
Thanks for sharing your question with us. Email marketing is a critical part of your online store's success, so I love that you are narrowing in on this. Let's take some time to focus on the different pieces of this puzzle.
How can you implement email marketing into your own Shopify store? Shopify has made it easier than ever to curate, design, and create content - and then send it all within the Admin.
In Shopify, go to Marketing.
Click Create campaign.
Click Shopify Email.
Choose an email template.
Click the To field to select from a list of your customer groups.
Enter a subject for the email.
Optional: Enter preview text to customize the text that appears after the subject in customer email inboxes. For example,
More fresh finds for your summer wardrobe.
Tip: Your sender email address, which will appear in the "From" field, can be changed under Admin > Settings > General > Customer email address. If you have an email address that uses a custom domain here, make sure to complete any authentication steps.
Please look over this information and let me know if I can offer any further guidance.
