Mailchimp
Email marketing. A Piksio image goes into Mailchimp as an ordinary image link. The platform fills in each recipient’s values, and Piksio renders their version when the email is opened.
Merge tags
Section titled “Merge tags”Mailchimp writes merge tags like *|FNAME|*.
In image links Piksio uses the URL-encoding form, *|URL:COMPANY|*, so a value like “Smith & Co” stays intact.
Built-in fields
Section titled “Built-in fields”Piksio maps these to Mailchimp’s own fields automatically:
| Piksio field | Mailchimp field |
|---|---|
first_name |
FNAME |
last_name |
LNAME |
Custom fields
Section titled “Custom fields”Any other field must exist in Mailchimp before you send. Audience → Settings → Audience fields and merge tags → Add a field, then set its merge tag. Tags can be at most 10 characters.
Mailchimp’s guide to custom fields

Section titled “Good to know”- Merge tags use the audience field’s tag name in capitals, e.g. FNAME.
- Contact merge tags don’t fill in Mailchimp test emails. Use Preview mode with a real contact to check them.
Check before you send
Section titled “Check before you send”- In Use in email, use Test the link with sample values, and again with unfilled tags. Both are free.
- Preview one real recipient in Mailchimp to confirm it fills in the fields.
