Animated Gifs don’t work btw.
Getting the G+ logo working was a bit complicated, the sending domain seemed to make a difference and I tend to use the numerical Google plus url as it is a sort of primary key.
More to follow and they’ll probably be a more formal post on the Pure360 blog early next week, stay tuned!
In order to get the G+ icon/logo:
The sending domain appears to need to have valid/working MX records.
The domain needs to have some sort of DNS link to the domain listed as the brand’s url on the G+ page.
– Tried it with a sub-domain of the domain listed on the G+ page and it worked
– Tried it with a sub-domain of a domain which redirected to the G+ listed domain and it worked
DKIM doesn’t seem to make a difference either way.
The GooglePlus url code is not required. If your sending domain’s dns is linked to the domain your confirmed as your site in Google Plus it just picks it up automatically.
The fact you can specify a GooglePlus profile link seems pointless because it won’t pull the logo unless the sending domain is linked and it’ll do the look up that way anyway.
Sent an email for the first time from a different brand, did not include the G+ data, in fact, tried to wing it by editing the publisher data to call a different image and changed the url/googleplus to just say image:
Gmail still pulled through the google plus image from the account, the only link was the sending domain and item url of their site.
Upon further investigation it seems one should be able to get the logo untie inbox from a different domain. The same form used for the transactional schemes also registers your domain with your company.. Testing to follow.
