Hey @sebastiantf thanks for this - how did you test your fix here? Do you have any screenshots?

[owocki]

speaking of testing; id be interested to know if this introduces any regressions too

[sebastiantf]

@danlipert, I was testing it using Chrome DevTools to apply the style and it looked good.

I shall now try the instructions by @owocki to generate an email with the new styles and post a screenshot asap.

@owocki I shall check and see if this update brings back any other issues.
