Sequences send from mailboxes your team connects under Sequencer › Mailboxes. Every email step needs at least one usable mailbox available to the sequence, and every send goes out under the rep who owns the enrollment.

​
Connecting a mailbox

Click Connect Google and sign in with the mailbox that should send. Salesfinity asks for a single Gmail scope, the one that allows sending and reading mail for that mailbox, and nothing else.
Google classes this scope as restricted. Until the app clears Google’s verification, a Workspace admin must first add Salesfinity as a trusted app in the Google Admin console. If the admin has not done that, Google refuses the sign-in with “access denied: admin policy enforced” and the connect dialog explains what to send to the admin. This is a one-time change per Workspace.
Google returns a refresh token only on the very first authorisation. If a mailbox was connected before and stops sending after a reconnect, disconnect it fully and connect again.

​
Pool and assignment

Every mailbox is either assigned to a rep or in the shared pool.
  • An assigned mailbox sends only that rep’s enrollments. Assigning a mailbox moves it out of the pool, so the pool is by construction the mailboxes nobody owns.
  • A rep with no assigned mailbox sends from the pool. If the pool is empty and the rep has no mailbox, their sequences cannot send and Enable on a sequence with email steps is refused.
  • A sequence can also be limited to specific mailboxes in its settings.
Use assignments preview to see which rep would send from which mailbox before saving a change.

​
Limits, warmup and health

​
Health

Each mailbox shows a health status based on its domain’s DNS: Open the mailbox and click DNS for the exact record, what was found, and the fix. Common ones:
  • No SPF record: receiving servers cannot confirm your domain authorised the send. This is the single most common reason cold email lands in spam.
  • Two SPF records: the standard treats this as an error and checks fail. Merge them into one.
  • SPF ends in ?all or +all: authorises anyone to send as your domain. End it with ~all or -all.
  • No DMARC: publish a _dmarc record, starting with p=none if you are unsure.
  • DKIM not found: Salesfinity tries the common selectors; if yours is custom, confirm DKIM in your provider’s admin console.

​
Test emails and placement tests

  • Send test email on a mailbox sends a real message to an address you choose, through the connected account, so you can check the from name, signature and tracking.
  • Deliverability › Placement tests (where available on your plan) send a set of test emails to seed inboxes at the major providers and report, per mailbox and per provider, whether they landed in the inbox, in promotions or in spam.

​
Disconnecting

Delete removes a mailbox. Active enrollments that were sending from it move to the owner’s other mailbox or the pool; if there is none, their next email step waits and the enrollment shows a failure reason until a mailbox is available.
