Responsive emails / Limitations – Splio Managed Services

General limitations of our service

We can't assure a perfect display on all email clients and devices
There are custom fonts related limitations. We can import custom fonts to the HTML design, but the font has to be hosted by the client. Moreover, custom fonts aren't supported on every email client. For example, MS Outlook always will show the safe font, instead of the custom font (learn more about safe fonts on MDN).
There is an email length limit on some mobile devices/clients
Images displayed on Outlook are blocked by default
Scripts (JS, PHP) don't work inside most of the email clients
Cutting-edge front-end techniques don't work in emails (e.g. flexbox, grid), the code must be based on tables
UTMs don't work in links with redirections
Dynamic URL won't work (Outlook, etc.)
Video feature doesn't work inside email clients (but video can be sometimes replaced by GIF)
The dark mode is a relatively new feature for emails and it's not fully supported yet. However, we can optimize custom HTML or template to dark mode, but as it's not standardized, we can't assure the perfect display on every device and email client.

There is no possibility to create complex or pixel-perfect designs, especially with mobile versions
Font management is limited. Only predefined fonts are possible (no custom fonts). Mobile text alignment different from desktop devices is also impossible.
The code of the email could be so heavy which will impact deliverability or visibility (clipping on Gmail)
No dark mode support

The text used in template instances should have a similar length, otherwise, it could break the neighbouring elements
Using live text with an image as a background is supported only in a few email clients, so sometimes image in the background could be invisible.
There is no drag&drop option in this tool

Using live text with an image as a background is supported only in a few email clients, so sometimes image in the background could be invisible.
Live text inside frames in images is highly not recommended. Mobile devices render fonts differently so we can't assure that the display won't break. Below example of the broken design on mobile:

There is no possibility to add or edit a conditional block using WYSIWYG editor. Every manipulation of dynamic blocks in WYSIWYG will break behaviour or/and layout.
In Message Builder conditional blocks are only possible to use in the module with custom HTML code
Conditional blocks won't work in responsive emails that are sent from non-Splio platforms

If you want to know more about creating conditional blocks or you want to copy some ready-to-use codes, you can learn here, at our Help Center.
