Hi @tiana, 

Thanks so much for being a part of our Klaviyo Community and for sharing this question! Can you clarify what type of email you included, ie. if its a @gmail, @yahoo, etc.? We generally do not recommend using an email address that is a @gmail.com, @yahoo.com, @hotmail.com, @aol.com, or @outlook.com address, as that does affect the deliverability of your emails. You can update your sending email address by following the instructions in this guide: How to Change the Sender Email Address

This Community post below will provide some more insight on Email Deliverability Best Practices 

Additionally, this full Help Center article on Understanding Deliverability Best Practices is also another helpful resource to reference! 

Thanks and have a great weekend, 
-Cassy
