BEST PRACTICE DESIGN TIPS
What do we get asked about most at Parrot Digital? Easy – Email Design
What’s the best email signature banner size? Which email banner images work best? Can Parrot Digital give hands-on help with email design?
It’s our users’ most popular subject for one simple reason…when it comes to email signatures and banners, design makes all the difference.
Below you’ll find our recommended email signature and banner specs and best-practice design tips so that, whether you design your own or use our design services, your email signatures and banners will get the biggest results with Rocketseed Email Signature Software.
Email Signature Dimensions
Signatures should be a maximum email signature width of 650 pixels and a maximum height of between 90 and 150 pixels.
Images within the signature design should be .PNG files with transparent backgrounds and should be designed to a web resolution of 72dpi to display correctly on 100% zoom view. While Rocketseed supports .JPG and .GIF images, with Dark Mode view becoming more prevalent, images with transparent backgrounds (i.e. PNGs) will better preserve the integrity of your design.
The email signature banner size file may not exceed 10kb (when optimized for web).
All email signatures will be converted to HTML, therefore you should use only ‘web safe’ system fonts in your design.
Email Signature Design Tips
Your email signature should embody your brand and engage your audience. And because consistency is key, make sure your signatures are completely on brand with regard to colours, fonts and logos.
Make your signature ‘social’ by incorporating relevant social media icons to promote your social channels – but only those that you’re actively managing and regularly updating. A link to a neglected social channel will only tarnish your brand and increase bounce rates.
Promote your newsletter sign-up form or blog in your signature. Use branded icons for the best effect. You can also take advantage of list builder, which comes as part of the offering from Rocketseed – to capture and manage sign-ups.
The key tip for all email signatures and email banner images is obvious (but often overlooked) – Keep all your contact details and calls to action clear and simple.
Things to note whether using Rocketseed or not
If you choose to use transparent backgrounds for images bear in mind that white, dark grey and black text may have rendering issues in either light or dark mode. Emails with images over the size of 15kb show the images as attachments in Google inboxes
Recommended email banner specs
We recommend a maximum email banner width of 650 pixels and a maximum height of between 90 and 150 pixels when designing a header or footer. This ensures that your email banner will be easily viewable (but not obstructive) in any preview pane or smartphone.
Headers and footers should be created as JPG or animated GIF files and should be designed to a web resolution of 72dpi to display correctly on 100% zoom view.
The email banner image file should be no larger than 40kb to ensure the additional ‘weight’ of the email is kept minimal.

These simple design tips can really make your email banners ‘click’, and get your audience engaged, whilst boosting your marketing campaign:
- Always include a compellingly clickable call to action
- Make your email banner images crystal clear (never pixelated!) and completely on message with your campaign
