Your contacts can have both a Birthday and Home Anniversary date added which may be used for automation events, to, for example, send an email to them automatically on those dates! For each data point, the day/month will be required, however the year is optional. The fields (birthday and home anniversary) themselves are optional as well.
When importing your contacts, we accept the following date formats in your CSV file, using August 11th 2021 as an example, resulting in a format of mm/dd/yyyy:
Aug 11 2021
Aug 11th, 2021
August 11th, 2021
The following format will be used for international dates, where the format is dd-mm-yyyy:
