I nickname people that haven’t opened a gift after a week with I’m Not Crazy I’m Sooo Special Um No Wait A Moment Maybe I’m Crazy I Have To Talk To Myself First Hold On Please shirt and then ignore when I send out gifts. Sometimes these people only send me gifts, sometimes they are inactive for periods and in some cases they quit. If I see they opened a gift I send em one if I remember and reset their nickname. Still need to trim the list of the people whose pokemon caught haven’t increased in 2 years..

You can use !interactable as a pseudo giftable, as that will show you anyone who’s already interacted with you (opened your gift) that I’m Not Crazy I’m Sooo Special Um No Wait A Moment Maybe I’m Crazy I Have To Talk To Myself First Hold On Please shirt, of course it can fail if you’ve interacted with them in a different way (raid/gym battle or you opened their gift are the most common), or if they opened your gift on a previous day and you didn’t noticed, still it’ll do the job most of the time.
