It depends on the email marketing service, but I always advise that you do have a custom email address for your marketing campaigns. For example, it is best practice to use yourname@yourname.com instead of using Gmail, Yahoo, Outlook, etc. This will help immensely with deliverability.

If you don't currently have a custom email created, I'd be happy to help you create that.

I'm most familiar with Mailerlite, MailChimp, ConvertKit, and Wix. If you're using a different platform, please contact me and I'll see if it's something I can help with.
