FAQs on Responsible, Deliverability Optimised and Responsive Email from Welkom Editor

All the email templates you create using our Email Builder and the pre-usable content blocks are guaranteed to have a Responsive design. They will automatically adapt to the device and screen size on which they will be displayed to your contacts. You can simulate how your email will look on all three screen sizes (computer, tablet and smartphone) in real time via the preview feature of our tool and also customise the mobile version if it is too image-heavy for instance.

None of the email tools strictly follow the W3C (World Wide Web Consortium) standard language and each one interprets the HTML code of their email messages differently. Many precautions must be taken to optimise delivery (contact management, email design, content, routing practices and tools). Welkom Editor only deals with the technical aspects of email design so that the HTML code is adapted to the specificities of this channel: “table” structure, languages limited to HTML and CSS, adapted tag for the definition of styles and image widths, encoding of special characters, automatic reduction of images and message weight, etc.
Welkom Editor also benefits from the experience of Dolist, provider of the solution and French specialist in email routing since 2000. Its development was carried out by its own technical teams, who have integrated all their know-how in terms of routing quality and sender reputation management. Its deliverability teams and its Design & Digital studio are also strongly involved in the development of the tool and stimulate the development of new features or the integration of trends according to the evolution of email marketing.

Absolutely! Our technologies include a very practical “Email Rendering” feature. With a single click, you can run a display test of your email on many email customers, webmails and browsers on the market, as well as on desktop, mobile and tablet devices and in Dark mode. More than fifty in total. Ideal for ensuring that your creation is as you expect it to be, regardless of your contacts’ equipment.

Our Email Builder incorporates content blocks which have been optimised for digital accessibility in accordance with the design standards in force (W3C-WCAG and RGA). Their use thus guarantees the creation of inclusive email communications, i.e. those which are easy to read, use and interact with for all users, including those with a visual, auditory, motor, intellectual and/or cognitive disorder or disability – temporary or permanent.
At the same time, our Design & Digital Studio has developed a real know-how in the conception of “responsible” email messages since 2020. Thus, it can undertake the creation of more specific or complex personalised email templates combining compliance with digital accessibility criteria, reduction of carbon impact, Dark mode, etc. This can also be applied to your landing pages.

In keeping with Dolist’s (the provider of the Welkom Editor solution) “responsible digital” approach, the design of email messages produced through Welkom Editor aims to optimise their overall weight. As a result, images and HTML code are automatically reduced to the bare minimum, without impacting the quality of the visual rendering. Lighter and therefore less energy-consuming, the messages also perform better in terms of deliverability. This is a virtuous circle which we strive to work on through each development of our tool.
To go even further in terms of eco-design, our Design & Digital Studio can also create for you templates and/or blocks of personalised email content which are more advanced in terms of reducing carbon impact, creating optimised design or even Dark mode.
