Question 1

What is the main benefit of hosting email images on a CDN (Content Delivery Network)?

Accepted Answer

CDN ensures faster image delivery by serving from servers geographically closer to recipients

Answer

CDNs distribute images across global servers, ensuring recipients load images from the nearest node for reduced latency and faster delivery.

Question 2

In what color mode should images be saved for use in email campaigns?

Accepted Answer

RGB

Answer

Screens display colors using the RGB (red, green, blue) model, so email images must be saved in RGB mode for accurate color rendering on all devices.

Question 3

When an email image fails to load, what is typically displayed to the recipient?

Accepted Answer

The alt text and a broken image icon

Answer

When an image fails to load, email clients display the alt attribute text and often a broken image icon, which is why descriptive alt text is essential.

Question 4

What screen resolution (DPI) is recommended for images intended for standard email display?

Accepted Answer

72 DPI

Answer

Standard screens display at 72–96 DPI, so saving email images at 72 DPI delivers sufficient quality without adding unnecessary file size.

Question 5

What was a 'spacer image' historically used for in HTML email layouts?

Accepted Answer

To create precise spacing and whitespace in email clients that lacked CSS padding support

Answer

Before reliable CSS support, designers used transparent 1x1 pixel GIFs as spacers to control spacing and layout in table-based HTML emails.
