Algorithm configuration

Mail clients impose certain limits. Splite lets you choose the behavior of the algorithm when it meets one of its limits. (see the limits of mailboxes).

Choice of HTML code export type
Splite generates a responsive HTML code for you. Once generated, this code must be imported in your sending tool (ex : Mailchimp or
🚨 There are different ways of working depending on the tool used.
We advise you to look at our guide "" to know which option to choose depending on your sending tool.
From the "Algorithm Setup" page, Splite offers you to choose between:
→ HTML export only: you get the HTML code as a copy/paste. Images are hosted on our servers
→ ZIP export: you get a ZIP containing the HTML file and the images.
Non-native fonts
Non-native fonts are not recognized by a large part of the mailboxes on the market (e.g. all Windows mail clients).
If you use a non-native typography in your email, Splite leaves you two possibilities:
→ Integrated in HTML/CSS: the text will remain dynamic & will be displayed well on compatible boxes. On the others, the typography will be replaced by Arial
→ Integrated in image: the text will not be dynamic (impossible to have a CRM tag for example) but the result will be visually identical on all mailboxes. Be careful, this option can cause problems with the "Dark Mode".
🚨 Attention, it is important to have a ratio HTML / Image text (that is to say all the elements generated in image) of 60/40 minimum for deliverability.
Additional information: If you use "Helvetica", "Times" or "Palatino", Splite will integrate it and put "Arial" or "Times New Roman" as second typeface.
Drop shadows
As for typefaces, drop shadows are not supported by a large part of the mailboxes on the market.
You then have two choices:
→ Embedded in HTML/CSS: the drop shadow will only be visible on compatible clients but the element will not be transformed into an image
→ Embedded in image: the element will be transformed into an image (or background-image) with the drop shadow. The shadow will be present on all mail clients but the element will not be generated in HTML.
Image quality
You can decide the quality of the generated images:
→ Standard compression: images are compressed to keep a happy medium between respecting quality and optimizing weight.
→ Maximum compression: images are compressed to optimize weight at the expense of a small loss of quality
