Set up a one-time or daily sync of your Follow Up Boss leads into Constant Contact

With Follow Up Boss, instantly transfer new leads and contact updates from Follow Up Boss to Constant Contact to keep your email lists up to date. Then, easily send campaigns to your contact lists with property listings of your choice. Select your desired template, edit the email design, and preview before sending your campaign.

Please note that this is a one-way sync. Newly added and updated contacts will not import from Constant Contact into Follow Up Boss. However, contacts that are unsubscribed in Constant Contact will sync back to Follow Up Boss.

Boost your marketing with the Follow Up Boss integration

Once your Follow Up Boss account is synced to Constant Contact, there are several ways to use the integration throughout your Constant Contact account:

  • Create a customized contact segment - When importing contacts from Follow Up Boss, they will be synced into segmented lists for you. But perhaps you want to segment these contacts even further to send specific, targeted messaging. You can do so by creating a custom segment of contacts.

  • Create an automated Welcome Path - Create a Welcome Path. When your list syncs, newly added contacts are automatically sent an email or SMS message.

  • Create an automated Anniversary Path - Send annual emails or SMS messages to your customers based on the date of their first visit to your business.
