EmailSyncerInstall on GHL
For Go High Level agencies

Send GHL emails from your real mailbox.

A workflow action that sends GHL emails through your real Microsoft 365 mailbox via OAuth. Pick the sender per workflow — your domain, your deliverability, your Sent folder.

Install on GHL MarketplaceSee how it works

GHL ships emails through Mailgun.

That’s a problem for three different reasons.

Deliverability

Shared sending infra, no domain-aligned authentication. Cold email lands in spam.

Sender identity

Replies don’t surface in the user’s inbox. Sent items never appear in Outlook or Gmail.

Compliance

Microsoft 365 DLP, retention, and encryption can’t apply when GHL bypasses the mailbox.

From install to first send in three minutes.

OAuth in, drop the action into your workflow, send. No SMTP, no DNS changes, no migration.

  1. 1

    Install on GHL

    One click in the GHL marketplace. EmailSyncer adds a Send Email workflow action and registers as your conversation provider.

  2. 2

    Connect a mailbox

    OAuth into Microsoft 365 (Google Workspace v2). We never see, store, or transmit your password.

  3. 3

    Add the action to a workflow

    Drop the EmailSyncer Send Email step into a workflow. Pick which connected mailbox should be the sender — emails ship via Microsoft Graph from your real account.

→ From install to first delivered email: about three minutes.

Built for agencies that send a lot of email.

Multi-mailbox by default, hardened where it matters, honest when something goes wrong.

Multi-mailbox per account

Connect every team member’s mailbox under one GHL install. Set defaults per location. Reconnections update; a different user creates a new mailbox row, never a duplicate.

Sent items, where they belong

Sends appear in Outlook / Gmail Sent folder automatically.

Smart attachment routing

Direct send for ≤4 MB, draft-then-send for larger. Automatic.

Encrypted at rest, locked down on the wire

AES-256-GCM for token storage. Ed25519 webhook signatures. OAuth 2.0 only — we never store a password, and audit trails record every event.

Per-mailbox throttle

30/min cap keeps Microsoft Graph happy. Bursts queue, never lost.

Friendly failure copy

When something breaks, the embed UI says why — in English.

Pricing

Frequently asked

  • Does EmailSyncer handle inbound mail?

    No — outbound only. Inbound replies still flow through your existing mailbox; GHL surfaces them through its normal conversation routing.

  • Does it work with shared mailboxes?

    Not in v1. Mail.Send.Shared support is on the post-launch roadmap.

  • What about Google Workspace?

    v2 — Microsoft 365 ships first, Gmail follows shortly after.

  • Can I send from an alias?

    Coming in v1.5. We already validate aliases against your mailbox’s proxy addresses at connect time, so the alias picker UI is the only piece left.

  • What happens if I disconnect a mailbox?

    GHL workflows that depended on it fail with a clear "mailbox revoked" reason. No silent drops — the embed log surfaces every failure.
