For the reason that header code controls the remainder of the e-mail, it’s crucial to verify every thing is right there first. That additionally consists of:
- Ensuring the e-mail is the right width (not more than 700px max)
- The code doesn’t consult with an exterior CSS fashion sheet
- There’s no unsupported components, like javascript or iframes
- Types conform to e mail code requirements, resembling utilizing 6-digit vs. 3-digit hex codes for colours
- Pictures are optimized for prime resolutions shows
That is additionally the place you possibly can be sure you’ve coded your tables and ghost tables appropriately in Outlook. And don’t neglect to verify different widespread Outlook rendering points like undesirable white traces, background pictures, and alignment points when utilizing columns.
It’s the basic 80/20 rule at play right here: You’ll probably spend 80% of your time taking a look at solely 20% of your shoppers, and Outlook is essentially the most problematic consumer you’ll run into…however it’s a must to work with it, as a result of it’s nonetheless the third hottest e mail consumer on the market.

- Proper font dimension for readability
- Columns and stacking work appropriately

Nevertheless it’s vital to be sure you’re streamlining your e mail code as a lot as doable. Pointless code weighs down your emails and will increase the scale, making them slower to load. Purchasers like Gmail clip emails at 102 kb, so preserve that in thoughts.
You’ll need to clear up spacing, padding, and your tables to verify every thing works correctly, too. There are a number of instruments on the market that may assist you to consolidate your code to lower the file dimension. I take advantage of E mail Comb or Parcel to take away unused CSS.

4. Do you may have fallbacks in place?
At the moment’s emails are extra personalised and customised than ever earlier than, and meaning complications for e mail devs. Fallbacks act as placeholders when information isn’t obtainable or supported. For instance, there are font fallbacks (aka font stacks) should you’re utilizing a customized font that an e mail consumer doesn’t assist.
Instance code snippet for a font stack
A sans-serif inline fashion font-stack may appear to be this:
fashion=”font-family: Helvetica, Arial, sans-serif;”

- Animations or different dynamic content material: Whereas most shoppers immediately assist GIFs, it’s nonetheless vital to verify any animations you’re working with have a nonetheless picture that you could present as a substitute.
- Personalization fallbacks: Nobody desires to obtain, ‘Hey, $%firstname%$’! Be sure to have copy in place in case there isn’t a primary identify on file, or no matter type of personalization you’re working with.
- Plain textual content model or a “View in browser” hyperlink: I’m nonetheless stunned how few manufacturers ship a plain textual content model alongside their HTML one. I at all times embody a “view in browser” hyperlink to verify emails are accessible and it’s a last-chance fallback simply in case one thing goes bizarre with the HTML.
For some assist with interactivity and dynamic content material, take a look at among the interactive e mail fallback methods we advocate right here on our weblog.

In case your viewers can’t learn or work together together with your emails…then why do all that work? That’s on the core of e mail accessibility: ensuring each member of your viewers can truly obtain the contents of your message. This implies checking for:
- Alt textual content on all pictures
- Desk roles set appropriately (function=”presentation”) so display screen readers course of your code appropriately after they learn them
- Utilizing semantic code, particularly <h> tags for headings and <p> tags for paragraphs, so display screen readers can differentiate between them
- That darkish mode is working appropriately in all e mail shoppers and never washing out the types (we’ll discuss extra about this in a minute)
Code snippet for setting desk roles
<desk width="100%" border="0" cellpadding="0" cellspacing="0" fashion="width: 100%;" function="presentation">
Utilizing function=”presentation” ensures display screen readers interpret the e-mail as physique copy and never information within the desk.

6. Is the e-mail code optimized for darkish mode?
Darkish mode is likely one of the latest additions to this guidelines, and some of the difficult. It’s grow to be fairly common — 44% of e mail entrepreneurs are contemplating the darker UX and one other 28% plan to begin making it a part of the e-mail manufacturing course of quickly.
The factor about darkish mode is, if it really works, it seems to be nice. But when it doesn’t, your e mail is just about unreadable.
