Below are a few methods for optimizing your marketing emails for mobile devices: 

Use a responsive email template

All of HubSpot's drag-and-drop email templates are responsive by default, meaning that your content will adjust to fit the screen it is being viewed on. Additionally, HubSpot adds a max-width automatically to images inserted in rich text editors including the email editor, so you don't have to worry about editing the source code to add max-width to prevent small, icon-sized images from blowing up to full width in emails on mobile.

If you are creating a custom-coded email template, be sure to take advantage of our responsive email template markup hereIt is also possible to purchase a responsive email template from our Template Marketplace.

Reduce image file sizes

In most cases, download speeds on mobile devices are slower than on desktop. Use smaller image files to decrease your email load time. HubSpot automatically compresses your images, as long as a width attribute is included on the <img> tag in the HTML of the page. You can learn more about automatic image resizing here. Services such as FastStone Photo Resizer and JPEGmini can also reduce file size by as much as 80% without reducing the quality of your image.

Increase the size of links and CTA buttons

To ensure your users are able to accurately click on your content on mobile, make sure any text links and CTA buttons are taller and wider than 57x57 pixels. Read more on the HubSpot blog here.

Preview your email on mobile devices

Before sending your email to your lists, you can preview what it will look like across different clients and devices.

Within the HubSpot email editor, click the Checkmark in the left-hand side to test your email in other email clients. Select the desired email clients within the Mobile section and click Test my email now to generate previews of what your email will look like when opened in those clients.

You can also use the device preview tool by clicking the preview (eyeball) icon on the left-hand side to quickly see what your email will look like on a desktop, tablet, or mobile phone.
