Connect your Yahoo!, Outlook, Hotmail or AOL email account to track interactions with contacts in your database.

One connected email address is free. If you need more than one connected email address, for $25 a month, you can connect up to 6 email addresses to your Kindful account. 


This article gives a brief introduction to Kindful's Mail Sync feature. This is a paid feature, and is separate from email marketing integrations (i.e. Mailchimp or Constant Contact).

What does it do?

When you connect an email account to Kindful using Mail Sync, Kindful will take record of every email that is sent between the connected email account and any of your contacts in Kindful.

You can connect your work email (e.g. to Kindful, to track email interactions with contacts in your database.

Any email exchanged with that contact will be recorded in Kindful as an email note, and will show in the corresponding contact's record.



Example A: Debbie Donor emails (Mail Sync enabled). Since Debbie has donated to the Matt's Hands organization, she is an existing contact in Kindful. When Jared sends an email to Debbie Donor, Mail Sync will create an email note on her contact record to track the email correspondence.

Example B: is not connected to Mail Sync. When Kate emails Debbie Donor, her email does not appear on Debbie's contact profile in Kindful.


How Mail Sync is shown in Kindful

Emails are shown as "Email Sent" or "Email Received" activities. Mail Sync will track every email exchange and detail the Sender, Recipient, email subject and email body. Attachments are not saved in Kindful.

When a donor sends you an email, including reply emails, a "sent an email" activity is added to the contact record. "Received an email" indicates that the donor was sent an email from someone using Mail Sync at your organization.



"Sent an email" activity and "Received an email" activity can also be found on your Activity Trail inside of Kindful.

To see your Email activity, Go to "Contacts & Activities", then click on "Activities", and then filter for the "Notes" activity type.

Pro-tip: Mail Sync adds emails to the General Campaign in your account. If you'd like to change the campaign for a specific email, you can edit that email activity's campaign by selecting Edit on the specific activity. Be sure to click Save when making edits to activities in Kindful. 

Sync Behavior

  • An email will only sync to Kindful if the contact already exists in Kindful.
  • You can prevent specific emails from being recorded by adding to the BCC field of any given email.

Example C: Fred emails Jared ( to ask about their donation needs. Fred hasn't given before, and his contact doesn't exist in Kindful. Because his contact doesn't exist yet, no parts of that email exchange are recorded in Kindful.


 Mail Sync won't track emails between you and your team

Sometimes the email connected Mail Sync will also send/receive emails from other staff members at the same organization. If that staff member has an existing contact in Kindful under their work email, Kindful automatically excludes all email addresses with the same domain name* (e.g., Any emails exchanged with that same domain will not be synced into Kindful.


One connected email is free. Upgrade for $25 per month for up to 6 users.
