- Image URLs will be converted from relative to fixed (eg. images/logo.png might change to http://www.esp.com/accountid/campaignid/tracking/logo.png) - if you have a large number of images in your email template then you can imagine every time that you have a relative URL it will be extended considerably.
- Furthermore links will be extended greatly for tracking purposes. So, even a URL like http://www.primelocation.com could change to https://edm.zpg.co.uk/pub/cc?_ri_=X0Gzc2X%3DYQpglLjHJlTQGgRnGbO6MYYw49tYrH4gcCiRRPYjqXzgzav3PyYCpoXcszfoHmzfndWOVXtpKX%3DACBYTT&_ei_=Eq2tf9zs59idfPO1Sc_9BblfScKRYOjPXUOrP0y84qY9EmGToqbo6zGNuVkeq1m9r0.
- Tracking pixels are usually, as standard, added into HTML emails so you can track opens, dwell time, location of opens, device statistics, etc.
- Dashboard (subject line, from name, address, reply-to, filter, audience, seed list, etc.)
- Rendering (desktop, tablet, mobile)
- Copy (spelling, grammar, relevance)
- Links (working, relevant, tracked)
- Personalisation (web version, unsubscribe, dynamic modules)
As Courtney mentioned there will be additions from the ESP. Just adding more detail to this:
I hope the above adds a bit more clarity and insight into what may be happening? :-)
You might want to declare a height and then have an "autoh" class which has height: auto !important; in your media query? Would that work for you to do that?
Our checklist is split out into five main categories:
These further breakdown. So, to check spelling and grammar we copy the entire email into word to see where any red lines may be appearing. For copy we check alt tags too.
There are services like KickDynamic which offer in-email instagram feeds. When it comes to a share button for Instagram there actually isn't a 'share' option available and Instagram's reasoning behind this is they want to keep their content current and high-quality too. You can see more details here: http://stackoverflow.com/questions/30542054/does-instagram-have-share-button-or-not - Hope this helps! :-)
Perfect answer! Thank you so much. I'll have a look into overriding styles and test it all through Litmus with a few third party examples. Always a challenge because we send about 30 third party campaigns each week (all from different agencies and all coded using different techniques). Fun times.
