Hello @BSiegfried,

Welcome to the Klaviyo Community!

Are you sending the email as a preview email or as a live campaign for testing? If you’re sending it as a preview email, this may be caused by hitting preview send limit. Our How to preview and send test emails in Klaviyo Help Center highlights the limits in the chart below:

If you sent the email as a live campaign for testing, I would suggest checking to see if the email bounced or was skipped. Both of these reasons can cause you to not receive emails despite previously receiving them in the past. 

I hope this helps!

Hello

I am having this problem now, can not send test emails to check a coupon code.

First, this is a ridiculous rule from Klaviyo, if you set restrictions like this, without a warning pop-up, how is the client meant to know! Even for me, as an agency I have just spend a wasted hour trying to figure out why this is happening.
 

Second, a test email should NOT be counted towards the clients monthly useage. We use test emails because we DO NOT TRUST Klavyio codes, and the Mobile view is always different to viewing on a real email.

After googling, I found I needed to update the client to the next tier, but am still not receiving the test email.

I can see 9 emails have been sent (which is the ones I’m sending to myself)

How else to fix this? Regardless of the client's account type or plan, there should be NO RESTRICTIONS on test emails. I’m really disappointed to learn this today. Such a waste of time and red tape for no benefit to anyway.

I agree with @studiocarly -- preview emails should be in no way connected to billing tier, profile usage, email send allowance/usage, or any other account level metric. What an absurd policy! Such basic functionality should fall within Klaviyo’s core offering for every customer.
