EMAIL PLATFORM · FORMATTED EXPORT
UK business data for Mailchimp
Export your selected contacts as a file laid out for a Mailchimp audience import, verified work email addresses with the company and contact fields you chose alongside them. Upload it to Mailchimp as a new audience or into an existing one.
What the export contains
- Verified work email addresses for your selected contacts
- Contact first name, last name and job title as separate columns
- Company name and any other fields you selected, for merge tags and segmentation
What to know
- This is a formatted export, not a live connection, records do not update in Mailchimp after the upload.
- You remain the sender and the data controller for anything you send; see our acceptable use policy.
From search to Mailchimp in three steps
Build your audience
Search 6.3 million UK businesses on more than 100 criteria, sector, size, location, turnover and the rest. Record counts update live as you narrow it.
Choose your fields
Pick what you actually need from 350+ company, contact and specialist fields. You see the cost before you commit, and you pay for the fields you selected.
Export for Mailchimp
Download the file laid out for Mailchimp, then upload it there. Suppression is applied first, so records you already hold are never included.
