Integrations

Booked55 integrates with Google Workspace and Microsoft 365 to enable email sending, calendar synchronization, and email signatures. All integrations use OAuth 2.0, meaning Booked55 never sees or stores your password.

Gmail integration

Connecting Gmail lets you send emails directly from Booked55 — both individual emails from contact profiles and bulk emails via campaigns.

1. 1

   Navigate to Integrations

   Go to Profile → Integrations from the sidebar.

2. 2

   Click "Connect Gmail"

   This opens a Google OAuth 2.0 authorization window.

3. 3

   Authorize access

   Sign into your Google account (if needed) and grant Booked55 permission to send emails on your behalf. Booked55 never stores your Google password.

4. 4

   Verify connection

   Once authorized, the Integrations page shows your connected Gmail address with a "Connected" status.

Microsoft Outlook email integration

Connecting Microsoft Outlook lets you send emails directly from Booked55 using your Outlook or Microsoft 365 account — both individual emails from contact profiles and bulk emails via campaigns.

1. 1

   Navigate to Integrations

   Go to Profile → Integrations from the sidebar.

2. 2

   Click "Connect Microsoft Email"

   This opens a Microsoft OAuth 2.0 authorization window.

3. 3

   Authorize access

   Sign into your Microsoft account and grant Booked55 permission to send emails on your behalf. Booked55 never stores your Microsoft password.

4. 4

   Verify connection

   Once authorized, the Integrations page shows your connected Outlook address with a "Connected" status.

Google Calendar integration

Connecting Google Calendar enables the Calendar View on the Activities page, showing your Booked55 tasks alongside your external calendar events.

The connection process is the same as Gmail — click “Connect Google Calendar” and authorize access.

Microsoft Calendar integration

Connecting Microsoft Calendar enables the Calendar View on the Activities page, showing your Booked55 tasks alongside your Outlook calendar events.

Click “Connect Microsoft Calendar,” sign in with your Microsoft account, and authorize access. Your Outlook calendar events will appear alongside your Booked55 activities.

Email signature

Below the email integration, you can set up your email signature. This signature is appended to every outgoing email sent through Booked55 — both individual and campaign emails, regardless of whether you use Gmail or Outlook.

The signature editor supports basic formatting (bold, italic, links). Keep your signature professional and concise with your name, title, and contact information.

Troubleshooting

• Connection expired — OAuth tokens can expire. If email sending fails, reconnect your email integration.
• Calendar not showing — Ensure you authorized calendar access (not just email). Disconnect and reconnect if needed.
• Send failures (Gmail) — Check that you haven't exceeded Gmail's daily sending limits (500 for free Gmail, 2,000 for Google Workspace).
• Send failures (Outlook) — Check that you haven't exceeded Microsoft 365's sending limits (10,000 recipients per day for business accounts).
