HubSpot email signatures, managed centrally
HubSpot Sequences, Sales Hub sends, and Meeting confirmations all route through your team's Gmail or Outlook inboxes. SyncSignature applies the correct signature at that layer. Your entire sales team stays on-brand without anyone touching their HubSpot settings.

How HubSpot and SyncSignature work together
SyncSignature does not connect to HubSpot directly. It does not need to. HubSpot Sequences, one-to-one sends, Snippets, and Meeting confirmations all send email through the user's Connected Inbox, which is their actual Gmail or Outlook account. SyncSignature operates at that layer. It connects to Google Workspace via the Admin SDK and Gmail API, or to Microsoft 365 via Microsoft Graph API and an Outlook add-in deployed through Microsoft 365 Centralized Deployment. Once those connections are in place, every email your sales team sends from HubSpot carries the correct, centrally managed signature because the signature is already in place on the underlying Gmail or Outlook account.
This is the only way to enforce a consistent email signature across a HubSpot sales team. HubSpot's own signature field is per-user, self-managed, and sits inside each rep's personal settings. There is no admin enforcement, no group-based templates, no link tracking on HubSpot native signatures, and no way to update the whole team at once. SyncSignature solves all four problems by operating at the Gmail or Outlook layer that HubSpot is already routing through.
What HubSpot Sequences do with your signature
When an SDR enrolls a contact in a HubSpot Sequence, each send goes out through the rep's Connected Inbox. HubSpot hands the email to Gmail or Outlook for the actual send. At that handoff point, the SyncSignature signature is already applied.
New SDRs are correct on day one
A new rep joins, gets provisioned into Google Workspace or Microsoft 365 through your HRIS, SyncSignature assigns them a template, they connect their inbox to HubSpot, and every Sequence they send from day one has the correct signature. No onboarding checklist item for setting up a HubSpot signature.
Marketing and brand updates propagate instantly
When marketing updates the signature template with a new logo, promo banner, or certification badge, the change deploys from the SyncSignature admin panel and every Sequence send from every rep picks up the new template on the next send. No one chases reps. No one asks 40 SDRs to paste new HTML into their HubSpot settings.
Link clicks on signatures are tracked
HubSpot's native signature field does not track clicks on signature links. SyncSignature does, at the Gmail and Outlook layer, across every email sent by every connected rep. If your signature has a Book a demo link, you see per-user click data for every Sequence in HubSpot without adding any HubSpot tracking.
HubSpot Marketing Emails are different
Marketing Email in HubSpot, the drag-and-drop email builder under the Marketing Hub, does not route through Gmail or Outlook. It sends from HubSpot's own email infrastructure. SyncSignature does not apply signatures to HubSpot Marketing Emails. This is a real limitation and the honest answer.
If your use case is signature management on 1:1 sales emails, Sequences, Snippets, and Meeting confirmations, SyncSignature fully covers it. If your use case is the footer of a marketing newsletter sent to 10,000 contacts, HubSpot Marketing Email handles that with its own footer configuration and SyncSignature is not involved. Most email signature management needs fall in the first category.
How to set this up
Typical setup: under 30 minutes
Connect SyncSignature to your email platform
If you run Google Workspace, authenticate SyncSignature with your Google Workspace super-admin account. SyncSignature connects via the Admin SDK Directory API and the Gmail sendAs API. One admin action covers the whole team. If you run Microsoft 365, connect your tenant via the Microsoft Graph API with read-only scopes and deploy the Outlook add-in through Microsoft 365 Centralized Deployment. Two consent grants. The add-in propagates silently to every user's Outlook within 6 to 12 hours.
Set up signature templates and targeting rules
Create templates in the drag-and-drop editor. Assign them to groups, departments, or roles based on directory attributes. New sales hire gets the sales template, customer success hire gets the CS template, based on their directory profile. No per-user setup.
Your team keeps working in HubSpot
Sales reps continue to use HubSpot Sequences, Snippets, Meetings, and one-to-one sends the way they already do. The Connected Inbox connection they already have to Gmail or Outlook is the integration surface. Every HubSpot send that routes through that inbox carries the SyncSignature signature automatically.
Manage everything from the SyncSignature admin panel
Template updates, banner campaigns, group assignments, analytics on signature link clicks. No changes needed in HubSpot. Ever. The only one-time step is asking reps to leave the HubSpot Connected Inbox signature field empty on initial rollout.
One HubSpot setting to check
HubSpot's Connected Inbox composer has its own signature field inside HubSpot settings. If a user fills in a signature there, HubSpot will append it to Sequences and sends on top of the Gmail signature that SyncSignature applies. The fix is simple and one-time: when rolling out SyncSignature to a HubSpot-using team, ask reps to leave the HubSpot Connected Inbox signature field empty. SyncSignature then operates without conflict at the Gmail or Outlook layer. You can verify the right setting by going to HubSpot Settings > General > Email in each user's HubSpot profile. The Connected Inbox signature field should be blank. This is the only HubSpot-side configuration change needed.

HubSpot and SyncSignature: common questions
No native HubSpot connector exists. SyncSignature operates at the Gmail and Outlook layer. HubSpot Sequences, one-to-one sends, Snippets, and Meeting confirmations all route through the user's Connected Inbox, which is their Gmail or Outlook account. SyncSignature applies the signature at that layer before HubSpot hands the email to Gmail or Outlook for sending.
HubSpot has two different email paths. Regular HubSpot emails composed inside the HubSpot UI use HubSpot's native signature field under Settings. Sequences and one-to-one sends go through your Connected Inbox, which is Gmail or Outlook, and use whatever signature is configured there. If you use SyncSignature, the Connected Inbox signature is the centrally managed template. If you only use HubSpot's native signature, only the HubSpot-composed emails get it and Sequences may look different.
HubSpot's native signature field is per-user only with no group logic. SyncSignature supports group-based signature targeting based on directory attributes. You can assign one template to the AE team, another to the SDR team, another to the CS team, all based on what your HRIS writes into the Google Workspace or Microsoft 365 directory.
No. HubSpot Marketing Email uses HubSpot's own sending infrastructure, not Gmail or Outlook. SyncSignature does not apply to Marketing Emails. For 1:1 Sales Hub sends, Sequences, Snippets, and Meetings, the signature does apply because those route through the Connected Inbox.
HubSpot's native signature field does not track link clicks. SyncSignature tracks clicks on all signature links at the Gmail or Outlook layer, across every email sent by every connected user. You get per-user click analytics on your signature in the SyncSignature dashboard, including emails sent from HubSpot Sequences.
One small step: ask users to leave the HubSpot Connected Inbox signature field empty. This prevents HubSpot from appending its own signature on top of the Gmail or Outlook signature that SyncSignature applies. No other HubSpot configuration is needed.
Log and send routes the email through your Connected Inbox (Gmail or Outlook). SyncSignature's signature applies normally. The email is also logged in HubSpot as an activity on the contact record.
No. SyncSignature reads employee data from your Google Workspace or Microsoft 365 directory. It does not request access to HubSpot contacts, deals, pipeline data, properties, or any CRM fields. The integration is purely at the signature layer, not the CRM layer.
Yes. HubSpot Mobile composes emails through your Connected Inbox, which is your Gmail or Outlook account. SyncSignature's signature is on that account and applies to every send from mobile, desktop, or web.
SyncSignature Teams at 20 users is $2 per user per month, billed annually. That is $480 per year total for 20 reps. 7-day free trial available with no card required. Pricing scales down to $1.40 per user at 100 users.
