LeadSquared Email Sync App

The Email Sync App allows you to capture leads and email activities in LeadSquared. It connects to your email server and synchronizes the received and sent emails.

  • Leads which are not present in LeadSquared will be created.
  • Received and sent emails will be posted as activities on respective leads.

You can control which emails are synced and which are not based on domains of senders and recipients, and also keywords in subject and body of the email.


  • Only the emails in “Inbox” and “Sent” folders will be synced. No other email folder will be considered for synchronization.
  • The Email Sync App will only work for email servers supporting IMAP protocol. Your users must be using IMAP as the protocol for your email client. If you use POP3 to send and receive emails, the sent emails will stay in your email client (Outlook, for example). The sent emails won’t be stored on our email server. If you use IMAP, the sent emails are synchronized and also stored on your email server. Since we connect to your email server to read sent emails, we won’t find them there if you’re using POP3.



You must be a LeadSquared Administrator user to install and set up the Email Sync App for your organization. Once the app is installed, any user can configure it to connect their inbox.

If your Email Sync App is already installed and you are looking to just connect your inbox, follow the instructions in – Email Sync App – Connecting your Inbox with LeadSquared

Email Sync Settings

  • Only emails to and from leads in LeadSquared:  se this option if you don’t want any email message other than to/from leads that already exist in your LeadSquared account. If you are in doubt, choose this option.

4. Excluded Domains

Additionally, you can exclude emails sent/received to/from certain domain.

  • Exclude emails if received on and sent from these domains (both sender and recipient on same domain”):  You can specify your own company domain so that your internal emails do not get synced.
  • Exclude emails if sent from these domains (incoming email): You can block sync of incoming emails from non-official, sensitive or social channels.
  • Exclude emails if sent to these domains (outgoing email): Use this setting to block sync of emails sent to specified domains, for example, emails sent to banks or financial companies. 
  • Click Save Settings once you have completed all the settings.

Note: Saving settings will not trigger sync immediately. Every LeadSquared user needs to connect their email account to LeadSquared before syncing starts.
