Create Once, Use Anywhere: How SendFox HTML Templates Work Across All Platforms (Yes, Even Thunderbird!)

If you’ve ever designed an email only to see it fall apart in another platform, don’t worry—you’re not alone. Email apps and marketing tools all render HTML slightly differently… which can completely break your formatting if you’re not prepared.

That’s exactly why SendFox HTML Templates are built in clean, platform-safe HTML that works everywhere and yes, even in the Thunderbird email app on your desktop.

Why universal HTML templates matter

Most templates are locked into one system.
Example:

• templates made for Mailchimp don’t always look right in Thunderbird

• templates created for Gmail break when used in Mailerlite

Universal HTML solves that long-term. With HTML, your design becomes platform-independent. You create it once, and reuse it forever.

Supported platforms (complete list)

✔ SendFox

✔ Mailchimp

✔ Mailerlite

✔ ConvertKit

✔ ActiveCampaign

✔ HubSpot

✔ Gmail

✔ Outlook

✔ Thunderbird desktop

✔ ANY platform with HTML support

➡ If there is a place to paste HTML, your template works!
