Tips for Creating Responsive Emails



This article outlines how to keep your email designs responsive across mail clients and devices so that your emails look consistent whether your reader is using Gmail, Outlook, Android, or Apple.

What is included:

Font Responsiveness

Many fonts are designed to be 'web safe' while some fonts are specific to the operating system; not counting fonts that are entirely custom. When sending to users across multiple platforms, you may see some of your font selections adjust based on which fonts are supported on the mail client or operating system.

Cross Platform Fonts

Sans Serif "Web Safe" fonts - The below fonts are your best bet for Sans Serif fonts that are compatible with most (if not all) platforms.

How Anchor Links (Table of Contents) are Treated Across Email Clients

We've noticed that more and more Communicators are using anchor links within their emails. They are a great way to quickly navigate through the email and provide for a helpful way to bring the recipient to a specific spot on the email. However, each email client (mobile or desktop) treats anchor links differently.

The two main anchor links that our customers use are: 

  1. Name Anchors: <a href="#anchorname">...</a> & <a name="anchorname">...</a>
  2. Back to Top Anchors: <a href="#top">Back to top</a>

The following table shows the different email clients and their treatment of anchor links:


* Anchor links are disabled as of iOS8

In the Internal Communications space, 90% of the email clients deal with anchor links just fine. Which is great news for Communicators!


When it comes to accessibility on the web for users with disabilities, there are various ways that websites introduce features to allow those users to continue accessing the content they are looking for in the easiest way possible.

Bananatag's website is designed with these considerations in mind, however Email Designs are typically user-driven, and as such there are still various ways that you can maximize the accessibility of your designs with a few simple tricks!

TIP: Use headings to convey meaning and structure

Use clear and descript headings to group paragraphs with related content. Good headings provide an outline of the content.



TIP: Make link text meaningful

Write link text so that it describes the content of the link target. Avoid using ambiguous link text, such as ‘click here’ or ‘read more’. Indicate relevant information about the link target, such as document type and size, for example, ‘Proposal Documents (RTF, 20MB)’, if linking to items like attachments.

TIP: Write meaningful text alternatives for images

For every image, write alternative text that provides the information or function of the image. For purely decorative images, there is no need to write alternative text.

TIP: Provide clear instructions

Ensure that instructions are clear, easy to understand, and avoid unnecessarily technical language. Try to describe the input type as best as possible (ex. smiles = 'how happy are you?')

While there are many industry standards as it pertains to accessibility, such as WCAG guidelines, these standards and principles primarily only apply to websites. There are no established accessibility standards for emails specifically, but you can utilize some of the below resources to help test and improve the accessibility of your communications.
