Just wondering how sendy handles duplicate data.
Is the newest data accepted and the old overwritten?
Is the new data ignored?
Are the the duplicated fields updated and the existing fields merged if nothing new is added.
I have tried some tests and it seems as though new data is ignored; just wanting to get a definitive answer.
For imported data with the same email address
When you import a CSV or use the "per line" method in Sendy's UI, Sendy checks for duplicates and will not import a record if one already exist in the list with a matching email address.
For signups via the signup form
When you add a user via the signup form or the API and if the email matches one that already exists in the list, any data you passed in, eg, name, or any custom field values will overwrite the existing data for the existing record.
Hope this helps.
Great that clarifies it!
