2. Merge Variable Error Checker
If a mail merge variable is left empty and <<>>, <>, or  are left present when sending, our system alerts that this is occurring and generates an error prior to sending.
As you can see in the screenshot, the blue arrow is pointing to row number, which identifies where the issue is occurring. The yellow arrow points to where you can confirm whether or not this is correct. The pink arrow points to the text box and where you can identify where the error is occuring and edit if necessary.
In order to continue, you must either confirm this is correct or make an edit to this. You will then be asked to confirm the number of recipients, and successfully send.
3. "Please Upload a UTF-8 Encoded CSV File"
This error will pop up if you have not saved the file in the correct format, or if there are special characters that are not allowed in the file. You may run into other formatting issues but to see the exact error you can visit csvlint.io to troubleshoot.
