ℹ️ Info
Part of the Getting Started guide, Step 2. Ensure deliverability.
Gmail can hold back or flag revel8 simulations as spam. This guide allows revel8's servers in three places in the Google Admin console: the IP allowlist, a spam filter exception, and an inbound gateway setting that removes Gmail's warning banners.
Before you begin
Have these ready:
A Google Workspace admin account for admin.google.com.
The revel8 values from Settings → Whitelisting (in Integrations): the entries under IP addresses and Email domains. Your revel8 contact can also send you the list.
⚠️ Warning
revel8 only sends from the email domains and IP addresses that are switched on in Settings → Whitelisting. After you add entries in Google Admin, switch on exactly those entries in revel8, and no others.
1. Add the revel8 IP addresses to the allowlist
In the Google Admin console, open Apps → Google Workspace → Gmail.
Open Spam, phishing and malware.
Under Email allowlist, add all revel8 IP addresses, separated by commas.
Click Save.
2. Create a spam filter exception
In the same Spam, phishing and malware section, under Spam, click Edit (or Configure) and name the setting, for example
revel8.Turn on:
Bypass spam filters for messages received from internal senders
Bypass spam filters for messages from senders or domains in selected lists
Bypass spam filters and hide warnings for messages from senders or domains in selected lists
For each list option, click Create or edit list and add the revel8 IP addresses and email domains. Untick Authentication required (received mail only).
Under the second option, bypass and hide warnings, choose Use existing list and select the same list.
Click Save.
3. Remove Gmail's warning banners
Even when simulations reach the inbox, Gmail can show a warning banner like this one:
Still in Spam, phishing and malware, find Inbound gateway and click Edit.
Configure the dialog:
Add the revel8 IP addresses under Gateway IPs.
Leave Reject all mail not from gateway IPs unticked.
Tick Require TLS for connections from the email gateways listed above.
Under Message tagging, enter any random string, for example
kzndsfgklinjvsdnfioasmnfsmf.Tick Disable Gmail spam evaluation on mail from this gateway; only use header value.
Click Save.
Check that it works
Send a test simulation to yourself. It should arrive in the inbox, not in spam, and without a warning banner.
