Begin on the high, naturally, with the header code, to ensure you’ve bought the proper DOCTYPE, language settings, in addition to meta tags set for responsiveness, darkish mode, and the right character set. This code not often modifications from electronic mail to electronic mail, however you by no means know if there’s a bizarre copy/paste factor happening.

Because the header code controls the remainder of the e-mail, it’s essential to ensure all the pieces is appropriate there first. That additionally consists of:
- Ensuring the e-mail is the right width (not more than 700px max)
- The code doesn’t seek advice from an exterior CSS model sheet
- There’s no unsupported parts, like javascript or iframes
- Kinds conform to electronic mail code requirements, reminiscent of utilizing 6-digit vs. 3-digit hex codes for colours
- Photographs are optimized for prime resolutions shows
That is additionally the place you’ll be able to ensure you’ve coded your tables and ghost tables appropriately in Outlook. And don’t neglect to examine different frequent Outlook rendering points like undesirable white traces, background photographs, and alignment points when utilizing columns.
It’s the traditional 80/20 rule at play right here: You’ll doubtless spend 80% of your time solely 20% of your shoppers, and Outlook is essentially the most problematic shopper you’ll run into…however you need to work with it, as a result of it’s nonetheless the third hottest electronic mail shopper on the market.
2. Is the e-mail code optimized for cellular?
On common, People examine their telephones 344 instances per day. With over 6 billion cellular customers on the planet, the second most necessary examine you can also make is to substantiate your electronic mail renders appropriately not simply on desktop shoppers, however on cellular ones, too.
Whether or not you’re utilizing mobile-friendly, responsive, or fluid hybrid electronic mail design, you’ll wish to examine:
- Button top of at the least 44px
- Proper font measurement for readability
- Columns and stacking work appropriately
Code snippet for a min-max width question:
@media solely display screen and (min-width: 400px) and (max-width: 600px) {...}
3. How clear is your electronic mail code?
While you’re constructing on older emails or re-using templates, electronic mail code can get messy actually rapidly. That’s since you typically need to create workarounds or hacks for particular electronic mail shoppers or performance.
But it surely’s necessary to ensure you’re streamlining your electronic mail code as a lot as attainable. 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 maintain that in thoughts.
You’ll wish to clear up spacing, padding, and your tables to ensure all the pieces works correctly, too. There are a couple of instruments on the market that may enable you consolidate your code to lower the file measurement. I take advantage of E mail Comb or Parcel to take away unused CSS.

4. Do you may have fallbacks in place?
At this time’s emails are extra personalised and customised than ever earlier than, and which means complications for electronic mail devs. Fallbacks act as placeholders when information isn’t accessible or supported. For instance, there are font fallbacks (aka font stacks) in the event you’re utilizing a customized font that an electronic mail shopper doesn’t assist.
Instance code snippet for a font stack
A sans-serif inline model font-stack may appear like this:
model=”font-family: Helvetica, Arial, sans-serif;”
You wish to double-check that you’ve got fallbacks in place so even when one thing isn’t supported, your viewers can nonetheless have interaction along with your electronic mail:
- Animations or different dynamic content material: Whereas most shoppers at the moment assist GIFs, it’s nonetheless necessary to ensure any animations you’re working with have a nonetheless picture that you would be able to present as a substitute.
- Personalization fallbacks: Nobody desires to obtain, ‘Hey, $%firstname%$’! Be sure you have copy in place in case there isn’t a primary title on file, or no matter sort of personalization you’re working with.
- Plain textual content model or a “View in browser” hyperlink: I’m nonetheless shocked how few manufacturers ship a plain textual content model alongside their HTML one. I all the time embody a “view in browser” hyperlink to ensure 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 a few of the interactive electronic mail fallback methods we advocate right here on our weblog.
5. Did you examine the e-mail code for accessibility?
In case your viewers can’t learn or work together along with your emails…then why do all that work? That’s on the core of electronic 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 photographs
- Desk roles set appropriately (position=”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 electronic mail shoppers and never washing out the kinds (we’ll discuss extra about this in a minute)
Code snippet for setting desk roles
<desk width="100%" border="0" cellpadding="0" cellspacing="0" model="width: 100%;" position="presentation">
Utilizing position=”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 among the latest additions to this guidelines, and one of the difficult. It’s turn out to be fairly well-liked — 44% of electronic mail entrepreneurs are contemplating the darker UX and one other 28% plan to start out 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 electronic mail is just about unreadable.
