Adding some data to this: 

When I sent an email to the email address mentioned above, I received a well-meaning automated reply. 

However, it contained the following part, which I don't think we should lead with:

In the meantime, why not check out some fun facts about Effective Altruism? Did you know that by donating to charity, you can save a life for as little as $3.33? Or that some of the most effective ways to make a positive impact are also some of the most unexpected?

This is inaccurate at best and deceiving and harmful at worst - and it's even debunked by the very link you follow this up with!^[1]

Hey! I'd like to quietly advertise a Job Post Template that I wrote.

TL;DR: If you have positions open, I think you're much more likely to get applicants if you mention things like salary, local-or-remote, part-or-full-time, without sending people to external links.

The post collects many such things that candidates care about and puts them in the same place.

For myself reading your post (giving my perspective as a single "user" of your post), I know many people who might fit your role as data analysts, but I know so little about the position that I have no idea if sending this post to them would be valuable or not.

I write this with the intention of helping and being useful, I might be wrong about everything, feel free to ignore.

Good luck! I hope your org goes really well

[Epistemic status: I've never done recruiting, I don't run or have a position at an 'EA org' - feel free to ignore anything I say]

But, a couple of thoughts:

1. Your branding and copywriting could use a lot of work. It's not immediately clear to me that this organisation is legitimate.
2. I'm highly unlikely to apply for a job if I don't know who the hiring organisation is. The organisation and their mission is one of the primary reasons I'll apply anywhere. If you're doing "blind" hiring rounds, you'll need to accrue a lot more trust amongst top talent.
3. These roles all seem fairly junior? I don't see much need for a recruiting agency working on junior roles. Main bottleneck seems to be finding a good fit for senior/management roles, and professional recruiters should rather spend their time on this

(V small feedback) Looks like you didn't actually hyperlink the website, so it's harder for people to find on a glance:

Maybe worth hyperlinking the first time you say the words 'Altruistic Careers' also?

A big thanks to everyone who commented on the post; we really appreciate all the feedback. Please feel free to leave any further thoughts on our project in the comment section or to reach out to me directly via [email protected].
