Gmail and Outlook (2-way email)
Connect your teamâs Gmail or Outlook accounts through OAuth and let Sellio automatically log every message sent and received on the right contactâs timeline. Itâs two-way sync: what you reply from inside the CRM goes out through your own mailbox, and what lands in Gmail/Outlook shows up on the matching deal. You keep using the same email you already have, and Sellio just ties every conversation to the relationship, with no copy-paste and no lost history when someone changes accounts.
- Connection via the customerâs own OAuth, with no exposed password.
- Automatic logging of sent and received emails as activities.
- Address-based matching to the right contact and deal.
Free in Sellio, you only pay for the machine
2-way email sync included: you only pay for the machine, never for this feature.
No typing up conversations
Emails land on the timeline by themselves. The team stops logging messages by hand and gets back to selling.
One history per account, not per inbox
Each rep connects their own account; the consolidated history lives on the contact, not trapped in individual mailboxes.
Reply without switching screens
You can reply to an email from inside the deal, and the message goes out through your Gmail/Outlook account, from your address.
Bring your own account: the Gmail/Outlook access token lives in an encrypted vault and is never shown on screen.
Truly two-way: replying in the CRM sends from your mailbox; receiving in email shows up in the CRM.
No add-on: email sync that other CRMs charge extra for is already included here.
OAuth, not a password
The connection uses Googleâs or Microsoftâs official sign-in. You authorize once, revoke whenever you want, and Sellio only receives a limited-scope token, kept in the vault and invisible in the interface.
The whole conversation next to the deal
Opening a contact, the team sees every email exchange with date, sender and subject, alongside meetings and tasks. Nobody has to dig through a personal inbox to see where the negotiation stopped.

Follow-up that doesnât go cold
The proposal sent by email already shows on the deal; a week later any colleague sees the customer didnât reply and picks it back up at the right time.
Handoff during time off
When the account owner is away, the stand-in opens the contact and reads the whole prior conversation, with no email forwarding needed.
Audit of what was agreed
The email that closed the deal stays attached to the timeline, with date and sender, ready to review.
Do I have to give Sellio my password?

Does it work with Google Workspace and Microsoft 365?
Yes, it connects Gmail and Outlook accounts through the customer's own OAuth.
Is this billed separately?

Is the sync only inbound or also outbound?
It's two-way: replying in the CRM sends through your mailbox, and what arrives by email shows up in the CRM.
How is the email matched to the right contact?
Through address-based matching, which ties the message to the correct contact and deal.
Does each rep need to connect their own account?

Can I revoke access after authorizing?
Yes, you authorize once and revoke whenever you want.
Do emails show up automatically on the timeline?
Yes, sent and received emails are automatically logged as activities on the contact's timeline.
