Email personalization guides
Every email platform hides its HTML block somewhere different, and a few ship a countdown timer of their own. Each guide covers one platform: where the block is, what the platform does natively, and how to pass its merge tags into a live timer or image.
Pick your platform
Countdown Timers
How to Add a Countdown Timer in ActiveCampaign
Has a Timer block of its own. When that's enough, and when to use the HTML block and %TAG% deadlines instead.
How to Add a Countdown Timer in AWeber
No countdown block and no HTML element: two ways in, plus Liquid deadlines that keep click tracking intact.
How to Add a Countdown Timer in Brevo
The HTML block in the Drag & Drop editor, contact attributes for deadlines, and the preview that fills them.
How to Add a Countdown Timer in Campaigner
An HTML element at step two of the builder, pasted through the HTML Properties panel.
How to Add a Countdown Timer in Constant Contact
No HTML block, so the timer goes in through the Image block's URL field, with one deadline for everyone.
How to Add a Countdown Timer in Drip
No HTML block in the Visual Builder: the image URL goes in an Image element's Source field.
How to Add a Countdown Timer in GetResponse
Has its own Countdown block. When that's enough, and Custom HTML for per-contact deadlines when it isn't.
How to Add a Countdown Timer in HubSpot
The HTML module, contact tokens for per-contact deadlines, and why you preview as a contact.
How to Add a Countdown Timer in Kit (formerly ConvertKit)
Has its own Countdown block. When that's enough, and the HTML Block with Liquid deadlines when it isn't.
How to Add a Countdown Timer in Klaviyo
The HTML block in campaigns and flows, profile and event variables for deadlines, and previewing against a real profile.
How to Add a Countdown Timer in Mailchimp
A Code block in either builder, merge tags for per-subscriber deadlines, and why test sends leave them blank.
How to Add a Countdown Timer in MailerLite
Has its own countdown block. This covers what it can't do: evergreen windows and per-subscriber deadlines.
How to Add a Countdown Timer in Omnisend
The native timer is paid-plan and fixed-date only. The HTML element and Liquid tags cover the rest.
Dynamic Images
How to Add Dynamic Images in HubSpot
Tokens resolve in an HTML - email module, so they can go straight into the image URL. The CTA module can't do this.
How to Add Dynamic Images in Klaviyo
Profile properties in the image URL, the special first_name tag, and fallbacks for missing values.
How to Add Dynamic Images in Mailchimp
Only a Code block works, only with *|URL:FNAME|*, and the image looks broken until live merge tags are on.
Your platform not listed? Alterable still works.
Alterable content is a simple image tag and link. If your email tool can insert an image, it can show real-time personalized content.
