Sensors Magazine Email Specifications and Best Practices


Advertisers should provide the following to asecondini@questex.com at least five (5) business days prior to scheduled deployment: 

  1. Broadcast-ready HTML file (please keep the text constrained to 700 pixels in width and file size under 35K. Images should be linked and hosted from your server)
  2. Subject line (please keep to 50 characters or less)
  3. Test email address (please designate a single individual to receive and approve test emails. Your broadcast cannot proceed without a signoff from this individual.)
  4. Text-only versions may be provided in addition to the HTML file


Best Practices:

  • Providing broadcast-ready HTML: Emails are not like print advertising, or even like website advertising/design. Be sure your email has a clear call to action. Email software, Internet Service Providers and various anti-spam filters have made even legitimate email broadcasting a challenge. We check and optimize HTML for viewing in Microsoft Outlook; web-based email programs have many different standards and therefore we cannot guarantee HTML will be viewed correctly on web-based email. The following points are designed to help you get your message delivered and read:
    • All-image emails trigger spam filters. Body copy MUST be html text. HTML should be at least 50% text-based/50% image-based.
    • Total width of HTML display should be 700 pixels or less.
    • You have only a few seconds to grab the recipient's attention - don't waste it with large images that take too long to load. File size for complete mailing (including images) must be less than 1MB. Preferred total file size is under 100KB (to load within 3.2 seconds on a 256 Kbps DSL line and have a better chance of being read).
    • CSS style tags are permitted, if embedded within the email (cannot LINK or IMPORT a stylesheet). Do NOT use CSS for absolute positioning.
    • Because some email browsers (especially web-based) remove the <HEAD></HEAD> section of html, CSS should be embedded (in-line) with each tag or, as a work-around, the <style></style> section can be moved to the very top of the <BODY></BODY> section.
    • Do not use FORM or SCRIPT tags.
    • Images should be hosted on your web servers. Be sure to use absolute URLs in the image tages (e.g., <IMG SRC="http://www.website.com/images/image3.gif">). Be aware that a large email broadcast can result in a concentrated heavy load on your server.
    • Use only .gif and .jpg formats — no .bmp, .png or flash files.
    • All emails are broadcast with an OPT-OUT MESSAGE and link. We append this to your email, so do not include any opt-out links within your email. Our opt-out will appear at the bottom, centered under your email.
    • Questex reserves the right to edit images and HTML to fit within accepted best practices in email marketing.
    • Provide a plain text file of the email (don't forget to include any text that might be contained in your images). We broadcast multipart alternative format emails, which include an html version and a text version of your message; recipients who can view html see the graphic version and all others see the plain text version.
  • Subject line: A good subject line should be short, descriptive and entice a reader to explore your message further.
    • Subject line should be 50 characters or less. It should start with an action verb such as learn, download, etc.
    • Please be mindful to stay away from overused, spam triggering words: Free, Help, Offer, Percent off, Reminder, Guaranteed and punctuation marks such as "!" and "?" should be avoided.
    • Providing localization, such as including a city name, can assist in achieving higher open rates.
