I do a particular kind of job. I'm assigned tasks (say assembling widgets) based on certain required criteria. When I've done my job, I email various requestors to let them know that what they've asked of me has been made and it's ready for pickup.
There are two requestors who always reply with wildly over the top gratitude. I email out a simple "Hey, Your widget is ready for pickup, you can find it at XYZ place", and I get a typical respone email of "WOW!!! You're such a star!!! Thank you so much!! <row of smiley faces>" . This is nothing artistic I do that they could praise. It's the equivalent of making a box that has 5 sides and a lid that opens when you want it to, it's functional, it's nothing spectacular at all.
It just seems so bizarre and jarring to be wildly thanked for doing my job. It's what I'm paid to do, why the ludicrous overpraise and thanks? I'd appreciate it if I were staying overtime to make the widgets, or working under ludicrous deadlines, but it's just day to day work. (Note that when I do go the extra mile, I do get thanked by my bosses for that, so it's not a case of being unnappreciated).
Is there anything I can say to get them to tone it down a bit, because it's really grating on my nerves that somehow doing my everyday job to normal standards of competancy is so miraculous it deserves the email version of a fireworks display? EVERY. SINGLE. TIME. It's making me feel pandered to, like they're praising a child for colouring inside the lines. It's earned for the equivalent of doing things like if you asked a chef to make a slice of toast and when he does, going "WOW! You're so amazing!!"
Or should I just be grateful they appreciate me and keep my mouth shut?
