Mailgun batch sending

Transactional email. A Piksio image goes into Mailgun batch sending as an ordinary image link. The platform fills in each recipient’s values, and Piksio renders their version when the email is opened.

Fastest way

In the Piksio editor, open your saved image and click Use in email, then pick Mailgun batch sending. It writes everything on this page for your own design, ready to copy.

Merge tags

Mailgun batch sending writes merge tags like %recipient.first_name%.

Mailgun batch sending doesn’t URL-encode values inside links, so keep personalized fields free of & and # (they can cut the link short).

Where to paste

Paste the HTML into the message, and give every recipient each value in recipient-variables.

Formats offered: Image URL, HTML. The default for Mailgun batch sending is HTML.

Example

For a design with first_name and company_name, the HTML looks like this:

<img src="https://app.piksio.com/i/YOUR_IMAGE_ID?first_name=%recipient.first_name%&company_name=%recipient.company_name%" width="600" alt="Your personalized image" style="display:block;max-width:100%;height:auto;border:0" />

Check before you send

1. In Use in email, use Test the link with sample values, and again with unfilled tags. Both are free.
2. Preview one real recipient in Mailgun batch sending to confirm it fills in the fields.
3. See Fallbacks and blanks for what a recipient with missing data sees.
