Email Sync App – Connecting your Inbox with LeadSquared

The Email Sync App allows you to capture leads and email activities in LeadSquared. It connects to your email server and synchronizes received and sent emails. Leads that are not present in your LeadSquared account 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 the subject and body of the email.


  • This connector is will be deprecated on 31st March, 2023, and we will stop providing support for the connector after the said date. It is mandatory you migrate to the new Email Sync (v2.0) connector before 31st March, 2023. To know more, refer to How to Migrate to the New Email Sync v2.0 connector?
  • Only the emails in “Inbox” and “Sent” folders will be synced. No other email folder will be considered for synchronization.
  • You must be using IMAP as protocol in your Email Client. If you use POP3 to send/receive emails, the sent emails will stay in your email client such as Outlook.   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 use POP3.
