Hello,
I have some questions about the Shopify Email Application and hope that the Community can offer some guidance.
When I use the Email application to create a campaign, during the editing process is the ability to send a test email very similar to MailChimp. However, I do not know if these sends occur immediately or go to some queue to send at a later time. Consequently it looks like some Send Tests never go anywhere and are never received at all.
I also find that if the target address for a Send Test is to a valid @gmail.com address, the test send NEVER arrives.
Perhaps someone could educate me on this. I have read some messages recommending Omnisend over the built in Shopify email, but I am trying to keep client costs down. Are there known limitations to Shopify Email? The Client is on the Grow plan.
The client is completely new to being online and their technical skills are developing when it comes to online selling and digital marketing, so simplicity is key right now.
Thank you
Ross Chevalier

Hey @Ross_Chevalier 
- we have a decent FAQ here that might answer some questions for you
In terms of the emails sending out right away, I can confirm that we use a process called “Batching” which does put emails into a queue to be sent later, though this wait time is usually not too long.
There are a few reasons why some emails may never be received (common reasons are spam filters for example, email address/IP hosts preventing emails from Shopify from being received etc.), but that one specific Gmail address not working is odd for sure.
For help with that specific Gmail issue, I think reaching out to our support team on help.shopify.com and linking this community thread would be the best bet to get that looked into.
Hope this helped a little bit, but let me know if I can clarify anything more on my end here. 
Thank you Alan. I did chat with someone in support today and that person was able to send test emails without issue, but they still tend to fail or be really delayed for me. There was no determination of root cause. The FAQ is indeed decent but nothing in it was useful in this case and I had already gone through it prior to posting the question.
Not optimal, but so it goes.
