It is possible to send campaigns with dynamic content (subject lines, greetings, etc.) to 250ok Inbox, but you will need to implement an x-header or hidden body tag to help us identify your messages as belonging to the same campaign. By default we will search for X-250ok-CID as a unique identifier, but your account may already be configured for additional x-header types. Go to 250ok Inbox > Settings to see which x-headers we can accept for your account. More information on x-headers is available here.
When users are seeking to send tests with dynamic fields to 250ok Inbox, 250ok will display whatever dynamic fields we first detect. (subject line, greeting, etc.) Results will display as follows:
Subject: Thanks for your order 250ok Support!
“Hello 250ok Support!

If you do not have profile information for 250ok Inbox seed addresses these dynamic fields will appear blank, as follows:
