Preview HTML letters in browsers and mobile clients

Many people are familiar with the sad situation when a well-formed letter on a mobile device or just in a certain email client looks like an unreadable mess of characters. This is not only insulting, but also harmful. There are several reasons for this:

1. The lack of uniform standards for displaying email-messages - this means that each mail service and email-client will show your letters as they like, depending on their own capabilities and available functions.

Although web browsers are more consistent and robust on this issue than email clients, they are also not perfect. And the final form of your letter, before it reaches the addressee, will change several times: first, under the influence of the postal service, and then transformed by your subscriber’s browser.

2. The growing popularity of mobile email - the rules for the formation of letters for reading on PCs and mobile devices are very different - this applies to both the size of the letter and individual details (the length of the letter's subject, images, links, etc.).

2. Blocking images - there is nothing to comment on; One of the most common problems that spoiled the look of a considerable number of letters.

You can solve this problem with the help of services that allow you to emulate the display of a letter in various email clients and browsers, both mobile and computer. Use them when you prepare your newsletter .

1. Analyzing a letter in various mail services and web browsers, and then finalizing the letter and correcting shortcomings and errors, requires a certain amount of time. Therefore, do not postpone it lastly, but do it at least 24 hours before the mailing.

2. Test letters not once, but at least once every 3 months, as browsers, email clients and applications are updated regularly.
