Forward your directory mail only - never your whole mailbox
Everything you forward to your Blastra address, we receive. Never point a blanket "forward all my mail" rule at Blastra - your private correspondence is yours, and we don't want a copy of it.
directories@your-company.comyou+directories@your-company.comCreate a Group
Go to admin.google.com -> Directory -> Groups -> Create group. Name it "Directories", with email directories@your-company.com.
Allow outside senders
In the group's Access settings, allow External -> Publish posts, so directory emails from outside your company are accepted.
Add your Blastra forwarding address as the group's only member
Copy your Blastra forwarding address from the panel and add it as the group's ONLY member. Mail sent to the group is now delivered straight to Blastra.
Google adds a small footer to mail it relays to external members - harmless, directories ignore it.
Add the forwarding address
Plus addressing is built into Gmail - you+directories@your-company.com already reaches your inbox, nothing to create. Gmail -> Settings -> Forwarding and POP/IMAP -> Add a forwarding address -> paste your Blastra forwarding address (in the panel). Google sends a confirmation there - Blastra confirms this automatically within a few seconds; wait a moment and continue.
Once the address is confirmed, Gmail offers you "Forward a copy of incoming mail to" on this same screen. Leave it switched off. It forwards your entire mailbox to Blastra, not just your directory mail - and because mail does reach us, the test below will still pass. Step 2 is what forwards the right mail.
Forward only the suffixed mail
Create a filter for to:(you+directories@your-company.com) -> "Forward it to" your Blastra address. This keeps the rest of your inbox private - only directory mail is forwarded.
A few directories don't accept "+" addresses; for those, use a dedicated address instead (switch the card above).
Create a shared mailbox
Free, no license required: admin.microsoft.com -> Teams & groups -> Shared mailboxes -> Add, e.g. directories@your-company.com.
Forward it to Blastra
Open the shared mailbox -> Email forwarding -> forward to your Blastra forwarding address (in the panel) - keep a copy if you like.
Allow external forwarding
Without this, forwarding works at first and then silently stops within a day - Microsoft blocks external auto-forwarding by default. Your admin: security.microsoft.com -> Email & collaboration -> Policies & rules -> Threat policies -> Anti-spam -> "Anti-spam outbound policy (Default)" -> set "Automatic forwarding rules" to "On - Forwarding is enabled".
Send this to your IT admin: "Please set Automatic forwarding rules to On - Forwarding is enabled in the default anti-spam outbound policy, so our directory mailbox can forward externally."
If forwarding stops and you can't get this policy changed, tell us - we'll find another way. Don't fall back to forwarding your own mailbox to Blastra: it looks like it fixes the problem, but it sends us your private correspondence, which we don't want.
Create a rule
Plus addressing is built into Microsoft 365 - you+directories@your-company.com already reaches your inbox, nothing to create. Outlook on the web -> Settings -> Mail -> Rules -> Add new rule: condition "To" includes you+directories@your-company.com -> action "Redirect to" your Blastra forwarding address (in the panel).

A few directories don't accept "+" addresses; for those, use a dedicated address instead (switch the card above).
Add an alias
Zoho Mail Admin Console -> Users -> your user -> add email alias directories@your-company.com.
Forward it
Zoho Mail settings -> Filters -> new filter: To contains directories@your-company.com -> Forward to your Blastra forwarding address (in the panel). Zoho emails a verification link to that address - it appears in your Mailbox here in Blastra (left nav -> Mailbox); open it and click the confirmation link.
Forward it
Zoho supports plus addressing - you+directories@your-company.com already reaches your inbox, nothing to create. Zoho Mail settings -> Filters -> new filter: To contains you+directories@your-company.com -> Forward to your Blastra forwarding address (in the panel). Zoho emails a verification link to that address - it appears in your Mailbox here in Blastra (left nav -> Mailbox); open it and click the confirmation link.
A few directories don't accept "+" addresses; for those, use a dedicated address instead (switch the card above).
Create the address
In your mail system, create directories@your-company.com - as an alias on an existing mailbox, a distribution list, or a new mailbox. Any of these work.
Forward it to Blastra
Set it to auto-forward to your Blastra forwarding address (in the panel). Some providers first email a confirmation link to the destination address to activate the forward - since that destination is your Blastra address, the email appears in your Mailbox here in Blastra (left nav -> Mailbox); open it and click the link.
Tell us your provider in support chat and we'll walk you through it.
Check plus addressing works
Most providers support it. Send yourself a test message to you+directories@your-company.com and confirm it lands in your inbox.
Forward it to Blastra
Create a rule or filter that forwards mail addressed to the "+" address to your Blastra forwarding address (in the panel). If your provider emails a confirmation link to the destination address, it appears in your Mailbox here in Blastra (left nav -> Mailbox); open it and click the link.
A few directories don't accept "+" addresses, and support for plus addressing varies by provider. Tell us your provider in support chat and we'll walk you through it.
