What is Linq Blue?

Linq Blue allows you to send iMessages (blue-bubble messages) from your CRM instead of traditional SMS.

Based on analysis of Linq user data, Linq Blue users see 86–116% more replies compared to SMS campaigns.

Key context:

iMessage has been in use on iPhone since 2011.
iMessage supports media (photos, video, audio), typing indicators, read receipts, and other features that standard SMS does not.
SMS is constrained by the original protocol and A2P 10DLC requirements, including mandatory opt-out language such as “Text STOP to stop.”

Linq Blue provides:

An iMessage channel that can connect to supported CRMs.
A way to keep business conversations inside a system of record (CRM or Linq app) instead of a personal Messages app.

Send and receive iMessages that support:
- Text
- Images
- Video
- Audio / voice memos
Use Linq Blue from:
- iPhone / iPad
- macOS
- Android (via CRM or Linq app workflows)
- Web / desktop CRM environments

To recipients on iPhone, messages appear as standard blue-bubble conversations.

Linq Blue connects iMessage conversations to supported systems:

Can be used inside GoHighLevel, Salesforce, HubSpot, and additional CRMs.
Messages can be sent from:
- Pipelines and deal stages
- Automation workflows
- Status changes and tasks (depending on CRM configuration)
Conversations can be viewed alongside:
- Contact records
- Notes, tags, and deal information

If you do not use a legacy CRM, Linq Blue can be used with the Linq app, which provides contact and conversation management.

Depending on the CRM and configuration:

Linq Blue can work with AI tools to:
- Suggest replies
- Summarize conversations
- Transcribe calls when combined with supported voice features

Linq Blue integrates with:

GoHighLevel (GHL)
Salesforce
HubSpot
Additional CRMs and tools via one-way sync or logging (e.g., Zoho, ActiveCampaign, Pipedrive, Zapier, and others).
Can be used for infrastructure

GoHighLevel
- Linq Blue can be set as a messaging provider.
- Workflow features work with Linq Blue when it is configured as the default provider.
HubSpot
- Requires a paid HubSpot service seat.
- Supports sending and logging messages against contacts.
Salesforce
- Requires Lightning or Enterprise edition and the Lightning UI.
- Messages can be logged on contact/lead records.

Linq Blue operates in the peer-to-peer (P2P) messaging space and does not rely on 10DLC registration for iMessage delivery.
Linq Blue does not require “Text STOP to stop” language in each message.
Linq Blue respects Do Not Disturb (DND) flags in supported CRMs:
- If a contact is marked as DND in GoHighLevel, Linq Blue will not send messages to that contact.

If a CRM displays A2P-related warnings, those typically apply to its built-in SMS provider, not to Linq Blue.
