I want to send marketing emails to around 1,400 people who interact with my site. I intend to repeat this two or three times a month. Which plan should I choose in this case?
I’d suggest checking out the email plans on your dashboard but the Core plan should let you send 5,000 emails monthly, in addition to other benefits like sharing your email in a web view with a custom domain and the ability to send from multiple emails.
As a rule of thumb, I’d suggest cleaning up the email list before sending to a larger amount of emails to help improve deliverability of your campaigns. This article also has some other tips as well: Email Marketing: Best Practices | Help Center | Wix.com
