Mail not sending

Hi @Sorcha and welcome to the Community!

I totally agree with @inboxingmaestro that the first step to resolve this issue would be to check any peripheral folders in your inbox, including spam, promotions (gmail), or social (gmail). You could also search your inbox for the subject line that you created in Klaviyo.

Klaviyo is responsible for sending your emails, but it’s successful delivery can be influenced by a number of things - mainly your inbox settings. Klaviyo is like a retailer that wraps and hands off a package to the post office, while inbox providers are like the delivery services responsible for the bringing the package to your customer’s doorstep.

To that end, if inbox providers don’t recognize your email address, have custom or native filters, or maintain a strict sorting protocol, your message might not end up in your primary inbox. Your email could also be sent to spam if it contains any rhetoric that providers flag as questionable, such as ‘money’, ‘win’, etc. 

If you check all of your folders and spam and still can’t find the email, you could try setting up the account with a net-new email address as my colleague Dov suggested in this thread:

Or, you could reach out to our D&C Team for support. Also, here is a Community thread and some Help Center articles discussing this topic:

I hope this helps, and thanks for using the Community!
