Frequently asked questions
Common questions about how to import contacts in mailchimp.
What file formats does Mailchimp accept for contact imports?
Mailchimp accepts CSV and TXT file formats for direct uploads. If you're using Zapier, the file format depends on your source application, as Zapier handles the data transformation automatically. For the best results, ensure your file includes email addresses and any other contact fields you want to import.
Can I import contacts from multiple sources at once?
Yes, you can set up multiple Zapier integrations to import contacts from different applications into the same Mailchimp audience. Each integration can be configured separately, allowing you to consolidate contacts from various sources.
What happens to duplicate contacts when I import?
Mailchimp automatically detects duplicate email addresses and prevents duplicate entries in your audience. If an email already exists, Mailchimp will update the existing contact record with new information rather than creating a duplicate.
How long does it take for imported contacts to appear in Mailchimp?
Direct CSV uploads typically appear within a few seconds to a few minutes. When using Zapier, the sync time depends on your Zapier plan and frequency settings. You can monitor import progress in your Mailchimp dashboard or through the Zapier interface.
Do imported contacts automatically receive a welcome email?
No, imported contacts do not automatically receive emails unless you specifically set up a welcome campaign or automation. You'll need to manually send a campaign or create an automation trigger to communicate with newly imported contacts.
