Email HTML and CSS rendering consistency

Business problem

Marketing emails and newsletters currently lose their original formatting, CSS, and styling when viewed within the Trengo inbox. This discrepancy between the platform and standard email clients makes it difficult for support and sales teams to accurately review, proofread, or test layouts before distribution.

Wished result

The ability to render incoming HTML emails with full CSS and style support, ensuring that fonts, spacing, and layouts are preserved. This would allow teams to reliably assess the visual quality of newsletters directly within the Trengo interface.
