Oh, yes: When was your last photo changed from selected for partner to Partner? How long they stuck as selected for partner before?
I had an image selected for partner changed to partner a week or two ago so the process still seems to work.
But indeed, not all selected images make it to a partner collection and I guess that's what you are experiencing.
They mainly seem to focus on Getty, but I also saw a few Adobe partner sales on Eyeem. So not sure how they report partner availability.
One partner that selects your image makes the status in your dashboard change from "selected for partner" to "partner" would sound logical.
Regarding Eyeem market sales: still happening, relatively decent commissions, but yeah, very scarce for me.
Earlier this year two of my images were selected by their curator and ended up in one of their own collections, resulting in a spike of likes and comments.
Thought I would hit a small jackpot there, but in the end I didn't sell a single license for those shots.
I can't really tell you what to do, but I generally prefer submitting to agencies directly instead of using something in between.
The exception is Wirestock, where I cherry-pick submissions for some of my content. I gave up Zoonar because of no sales.
And regarding Eyeem... well, being deadly honest with you: I have images on Eyeem which were previously uploaded to iStock, yet, they still made it to the Getty collection. Never got a complaint. A lot of others did and were asked to delete those images. I decided to keep them and I'll see what happens - I couldn't care less. Eyeem accounts for only a tiny fraction of my MS income, monthly coffee money at best, so if that gets suspended I would probably not even notice it.
I understand why you want to expand your exposure, but Eyeem should be very low on your priority list if you ask me.
Submit to iStock directly instead. Way higher acceptance rate and a better monthly income.
Unless you don't want to deal with their complex keywording interface. In that case: dump it on Eyeem and don't look back.
