Hi @Mark Guldbrandsen65! Are you testing with emails sent to yourself, or are these emails sent to your list? If they're delivering to yourself, your email client might think that it's spam because you didn't send it from within the email client. If this is the case, then just go ahead and drag those emails in your own account to your inbox.
Hopefully, this helps, and welcome to the ConvertKit fam!!
If you've got some time this coming week, @Haley C 54 and @Angel Marie 65 are running a challenge that you might be interested in. Here is the link to sign up87 and here are some more details here inside the community65.
