My inbox is full of rubbish ads - it overwhelms the stuff I care about, and makes my life sadder.
It always a pain point and someone somewhere is certainly not receiving something they feel they should. These services help because of how complex the email ecosystem has become with layers of identity and reputation and such.
That doesn't work for me; I am not a "use-case". I'm an individual person, and my choice is to not receive unsolicited advertising. Marketers don't seem to understand that some people object to receiving "helpful product suggestions" all through the day.
>>KERPLUNK<< another catalogue book just fell through the letterbox, and is destined for the recycling bin. Dammit, save me the trouble; just put it in the bin yourself, it's just by the front door. Hell, the bin's big enough; put the whole batch in my bin, end your shift, and go back to bed.
This sounds like you're saying it's a nasty job, but someone has to do it - like cleaning toilets, or assassinating tyrants.
Just stop.
It all makes me feel ill, to the very depths of my Soul.
"Order confirmations": not necessary. I should have a choice whether I use my email address to confirm an order.
"Transactional": I don't know what that means (I keep finding that term being used). I think it means that the email is being used as part of an agreed deal. Fine: if I've agreed to my email being used as part of a deal, no prob. Otherwise, leave me alone.
"Order confirmations": if I need my order confirmed, then I can opt for that, and give you my email. But in general, orders don't need confirming - you either order, or you don't.
"Password reset": My passwords are my business. I use a password manager. Please don't assume I'm a password slob. Passwords suck; they are an insane way to authenticate, they just don't work. So reset emails are not a good use-case for unsolicited email.
Next?
isn't their reason for existence the sending of multi-recipient emails?
It's not "necessary", same as Stripe isn't necessary for accepting payments but it makes it a whole lot easier if you have to deal with it and don't want to implement everything yourself or run mail infrastructure.
