>it feels less like marketing spam when there's nothing to click through

thats wild. im curious if u used sendgrid for this or some other provider. i always worry the mail servers will just flag it as broken metadata or something ❓

metadata errors are unlikely to happen if the header is just empty. most of the time that's going to trigger a spam filter immediately because it looks like a malformed packet. i'd expect the deliverability to tank rather than see an open rate boost. tbh i doubt sendgrid would even let you push through something that broken without a warning ❌

anon is right about the filters though. if you leave it truly blank, gmail's gonna think your smtp is dying and dump you in junk. if op wants that 'no subject' vibe without the deliverability suicide, just use a single period or an invisible zero-width space. works great for receipts where you want that boring look, but don't try this on any newsletter or promotional blast because it'll get nuked instantly. i tried a similar thing with ultra-minimalist headers last month and the bounce rate stayed fine as long as the sender name was solid. spoileri mostly just use it to hide the fact that my copy is trash/spoper lol.
