Quite frequently, our customers code their own email templates or acquire all of them coming from a designer, and also our team’ll acquire inquiries asking why an offered email verification appears various between what is actually been coded, what is actually received Customer.io, and what is actually sent to a specific person.

There are a couple of causes for this:

  1. HTML and also CSS job in different ways in e-mails and also the internet.
  2. Emails and how they’re set out (Layouts) bothfunction a little bit of differently in Customer.io

In this doc, we’ll attempt to detail explanation # 1, show how those variations show up in emails, and also hopefully offer some good advise for how to progress. (Below’s more details on reason # 2.)

Why does this take place?

HTML like header, footer and paragraphtags incorporate indicating to the information inside, as well as exterior CSS provides design and framework (factors like show, float, or even font-family).

Emails, having said that, are actually an entire various another tune. They level and checked out in a large variety of customers without any one specification between them. And inside lies the issue:

Email customer variances

Desktop, web, and also mobile phone email clients all use various motors to leave an email. (E.g., Apple Mail, Outlook for Mac Computer, as well as Android Mail utilize WebKit. Overview 2003 uses IE, while Overview 2013 makes use of Phrase.) Internet customers will make use of the internet browser’s motor. This assortment means that your e-mails are going to likely look various throughout web browsers, given that & hellip;

  • separate CSS documents are actually a no-go. All code needs to go in the email.
  • any CSS that isn’ t inlined is commonly removed.
  • no CSS shorthand!
  • clients could add their very own CSS. For example, Gmail is going to establishall << td>> typefaces to font-family: Arial, sans-serif They might additionally perform funny things like bit out product lines of code that begin along withdurations.
  • your images are likely blocked by default, and a customer may or might certainly not find them.
  • forms are actually irregular, as are actually online videos (yet gifs are usually supported!)
  • ” receptive” emails are complicated and also assistance wherefore “responsive” methods can easily transform across customers.
  • CSS residential properties like display: none; may not be assisted anywhere, and also neither are rounded corners.
  • font assistance beyond the standard isn’t excellent, either

As an outcome, an email that looks one way in the code publisher might appear various in Customer.io, may look various in Alice’s email client, and might look various in Bob’s email client.
