Email Message: All messages must be in .html format. A text version is recommended but not required. If you would like assistance, please inquire for a quote.

  • HTML Version: (.html file format). All images should be hosted. Image hosting is available for a small additional fee.
  • Plain text version: no dynamic links (they should all be spelled out), no images or special characters. (.txt file format).  This is not required but is suggested for recipients that have high-security settings and only receive plain text messages.

From Line:  The from line of each message will say: ENDO 2025 on behalf of (Your Company Name Here).  

Subject Line: Create a subject line for your message. You are encouraged to keep it under 50 characters to avoid truncating on computers. See section below form more information about subject lines on desktop and mobile devices.

Snippet/Pre-Header Text: When viewing an inbox, an email snippet is the very first line of text that your email recipient will see, following the email subject line. Some good practices when determining your snippet:

  • Snippets should remain between 30-70 characters in length.
  • They should be a continuation of the subject line.
  • Include a specific, actionable CTA to encourage readers to open the message.

See section on Subject Lines & Preheader text below for more information.

Seeds/Decoy Email Addresses: Email addresses for yourself and colleagues (if requested). These email addresses will be used to send a test of each message for approval as well as the final deployment of your message.

HTML Guidelines

1. General Email Coding Guidelines

  • Use tables for layout instead of divs, as many email clients do not support complex CSS positioning.
  • Stick to basic HTML (avoid JavaScript and external CSS, as most email clients block them).
  • Keep your design simple by using table-based layers and avoiding HTML floats or positioning.
  • The width of your emails should be 600-800 pixels (must be a whole-number pixel value).

2. Inline CSS for Styling

  • Use inline styles instead of external stylesheets.
  • Keep styles simple: font styles, colors, padding, and margins.
  • Use fallback fonts to ensure consistency across email clients (e.g., font-family: Arial, sans-serif;).

3. Fonts in Emails

  • Use whole-number font sizes (e.g., 10px instead of 9.5px).
  • Email-Safe Fonts: Arial, Courier New, Georgia, Helvetica, Lucida Sans, Tahoma, Times New Roman, Trebuchet MS.
  • Web-Safe Fonts: Lato, Open Sans, Oswald, Oxygen, Poppins, Quicksand, Merriweather, Raleway, Roboto, Rubik, Ubuntu.
  • Custom fonts may not display properly in all email clients. Limit their use to logos or images.

4. Responsive Design (Mobile-Friendly)

  • Use media queries for responsiveness (note: not all email clients support them).
  • Make sure text and images are mobile-friendly (use a 600px width for the email body).
  • Ensure links are easily visible and clickable on mobile devices.

5. Images & Accessibility

  • Use img tags with alt text for accessibility and fallback support.
  • Keep image file sizes lightweight. Example: A complex JPG at 500px by 500px should be around 100kb.
  • Make sure image dimensions use whole-number pixel values.
  • Do not design an email that is one large image—this increases the risk of spam filtering and reduces accessibility.

6. Avoid Unsupported Features

  • No JavaScript (most email clients block it).
  • Avoid complex CSS like flexbox, grid, and background images (they may not render properly).
  • Do not use Flash-based elements. If you need animation, use a .GIF instead.
  • Do not use a PDF-to-Email converter or Word processing software—they generate incompatible code.

7. Additional Best Practices

  • Use as few columns as needed to keep emails simple and readable.
  • Avoid overlapping visual elements.
  • Include text content in the email—never send an email with only an image.
  • If you’d like a view online link, include a blank row at the top with one of these: “View Online” or “View in Browser”
    • Use # as a placeholder, or {{~~ViewAsHtml~~}} to have the system generate the link automatically.
  • Include a contact method—the send/reply address is not monitored in real-time.

8. Opt-Out & Compliance

  • An opt-out statement is provided, but you are not required to add one.
  • Include a blank row at the bottom as a placeholder.

Subject Lines & Preheader Text

Email Subject Lines 

Here are some tips for effective subject lines:

  • Keep it short: Especially for mobile users, brevity is key.
  • Limit punctuation: Excess punctuation can make your email appear spammy.
  • Test and optimize: Regularly test different subject lines to learn what resonates with your audience.

 Character Limits by Platform

  • Gmail (Desktop): 70 characters
  • Gmail (Mobile): 38 characters
  • Yahoo Mail (Desktop): 46 characters
  • Yahoo Mail (Mobile): 40 characters
  • Outlook (Desktop): 60 characters
  • Outlook (Mobile): 30-40 characters
  • Apple Mail (Desktop): 60 characters
  • Apple Mail (Mobile): 40 characters
  • iPhone Mail App: 35 characters
  • Android Mail App: 30-40 characters

Tip: Most platforms display around 50-70 characters on desktop and 30-40 on mobile before truncating. To improve visibility, aim to keep subject lines under 50 characters for optimal display across all platforms.

Pre-Header Text (aka Snippet)

The optimal length for preheader text in email is generally 40-100 characters to ensure it displays fully across most email clients and devices. Here are some best practices to make the most of your preheader space:

  • Keep It Concise: Shorter is better to ensure it doesn’t get cut off. Aim for around 40-70 characters if targeting mobile viewers.
  • Complement the Subject Line: Use the preheader to add context or emphasize a call to action that supports the subject line, encouraging recipients to open the email.
  • Avoid Repetition: Don’t duplicate the subject line. Instead, provide a teaser or additional details to spark curiosity.
  • Front-Load Important Info: Mobile devices may cut off longer text, so place crucial words or phrases at the beginning.
  • Include a Clear Call-to-Action (CTA): If appropriate, add action words or phrases to prompt the reader to take the next step.
  • Avoid “Invisible” Filler Text: Many email clients show the first text in your email if you don’t specify preheader text. Don’t let boilerplate text or alt text appear in its place.

Keeping these tips in mind will help create preheader text that engages users and increases email open rates across platforms.
