Troubleshooting Tips
When creating domain level rules, do not include the “@” symbol.
Keep the file size under 2000 rows. If you need to upload 2000+ rules, creating multiple CSV files is recommended.
If your upload is failing, check your CSV to ensure that it is following the template format and that the file type is correct. Ensure there are no invalid symbols, whitespace, or invalid domains/addresses.
If you need to create an allow or block rule for an IP address, please create a “Custom Rule”. More information can be found here: https://docs.emailsecurity.app/help-center/creating-a-custom-rule.
Tip: You can combine allow and block rules into one list for importing as long as it remains under the maximum limit of 2,000 rules. This can be performed using the “Upload CSV” button in either the Allow Rules page OR the Block rules page. Allow rules will appear in the allow page and vice versa.
