If a merge tag cannot find the corresponding data for a particular recipient, the tag is replaced with an empty string (blank). No brackets, placeholder text, or error messages will appear in the sent email.
Common scenarios where a tag resolves to blank:
- [TotalDonated] — The recipient has never made a donation
- [MembershipLevel] — The recipient is not a member
- [RenewalDate] — The recipient has no active membership
- [Nickname] — No nickname has been entered on their constituent record
- [MailingAddress] — No mailing address on file
- [Phone] — No phone number on file
Best practices for handling missing data:
- Write your email so it still reads naturally if a tag is blank. For example, instead of "Dear [FirstName]," consider "Dear [FirstName] [LastName]," so at least one name appears.
- Avoid sentences that depend entirely on a tag being present, such as "Your total giving of [TotalDonated] has made a difference" unless you know the recipients are donors.
- For donation or membership tags, only use those tags in emails being sent to lists that you know contain donors or members.
- Use the [OrganizationName] tag freely since it always has a value from your account settings.
