Email on Acid Likes & Dislikes

Like

Multi platform testing (Gmail, Yahoo, Outlook etc...) Spam testing Recomendation on images links the overall email length and such

Like

Email on Acid does exactly as it says on the digital tin. Honestly, being able to incorporate it into pre-deployment checks takes a huge weight off my shoulders, knowing that not only these checks have been performed but that we can reach as many people as possible on their devices as we originally intended. I've used some competing software or functions that aim to replicate this built-in to other software before but AoA delivers so much more. The improvements to our QA deployment time were fantastic and gave a real framework for helping with some colleagues that needed some extra guidance. Overall, implementing this was beneficial to our revenue from campaigns as more users were able to see our campaigns as intended on their chosen platform.

Like

- Easy to navigate and appealing design - comprehensive email rendering tests - fast email tracking code generator - Cost, very reasonable and you are not committed to a long term contract

Dislike

Pricing is one thing that would make a smaller business stay away. And the occasional glitches of not loading is another.

Dislike

EoA sometimes gives a bit of a misnomer, especially when you start using it, because it will give you red alerts that your email isn't displaying as intended on all sorts of browsers and the first port of call is to feel underwhelmed and panicked. Usually these are lesser-used browsers and you can aim to prioritise browsers and email clients that the majority use and have the confidence that you're reaching as many as feasibly possible.

Dislike

- slow email rendering test. sometime it takes a while to see all the results - wish there was a bigger discount on the platform with longer commitment - lack of 24/7 customer support

    Email on Acid is a great solution to have the confidence in email campaigns before deploying them to a live audience. We've all had the sudden thoughts of what if...? after setting a campaign live (usually in the middle of the night) and Email on Acid gives the ability for a comprehensive checklist and confidence that emails will display correctly and be legible as intended to an audience.
