TL;DR
- Speculative recruitment emails still work, but they’ve always been a low-engagement play, and everyone in recruitment knows it
- What’s changed is the deliverability landscape: low open rates and spam complaints now actively damage your domain reputation in ways they didn’t two or three years ago
- The numbers game has a new cost, and most recruiters haven’t noticed yet
- The fix isn’t to abandon spec emails. It’s to make them worth opening. That starts with stopping being the hero of your own email
Think about every story you’ve ever loved.
Every film, every book, every series you couldn’t stop watching. They all follow the same pattern. You meet someone whose world isn’t quite right. They try to fix it. They struggle. They get sold a few promises that don’t deliver. And then, just when it looks like it might not come together, they find the thing that changes everything.
Who’s the hero in that story?
It’s not the wizard. It’s not the sword. It’s not the magic elixir. It’s the person whose world got better.
Here’s why that matters if you’re a recruiter whose emails are going unanswered, or worse, going to spam.
Spec emails still work. That’s not the problem.
Let’s be clear about something before we get into this.
Speculative recruitment emails are not dead. They work in the right market, with the right candidate, aimed at the right client. There are sectors where a well-timed spec email is still a perfectly legitimate way to start a conversation, and any recruiter who’s placed candidates off the back of one this year will tell you that.
But they’ve always been a numbers game. Send enough, and something sticks. Reply rates have never been high, and the industry has always known that. Low engagement was the accepted trade-off for reach.
The problem is that trade-off has quietly changed terms, and most recruiters haven’t read the small print.
What’s changed in the last two years
Gmail and Microsoft now pay close attention to how recipients interact with your emails. Not just whether they reply, but whether they open, whether they delete without opening, whether they move you to junk, and whether they hit the spam button.
These engagement signals feed directly into your domain’s sender reputation. A domain that consistently produces emails that get ignored or marked as spam is a domain that inbox providers start treating as a problem. Emails get filtered more aggressively. Deliverability drops. And the recruiters sending them often have no idea it’s happening. There’s no error message. The email just quietly stops arriving where it was meant to go.
The numbers game always had a low reply rate. What it didn’t used to have is a cumulative cost to your ability to send emails at all.
That’s new. And it changes the calculation.
The hero problem
So: why do spec emails get low engagement in the first place?
Read back any speculative email sent in the last month, yours, a competitor’s, one you received yourself. Notice who is the subject of every sentence.
I am representing. They are looking. They would be a great fit. The recruiter is the main character. The candidate is the supporting act. The hiring manager, the person who has to decide whether to open the email, let alone reply, barely features.
Nobody is compelled by an email about someone else’s story.
Think about what that hiring manager is actually dealing with right now. They’ve got a role they’ve been trying to fill for six weeks. Their line manager is asking questions. The last few CVs weren’t close. They’ve had conversations with two agencies who promised to come back and haven’t. They’re managing expectations with the business.
Your email arrived and mentioned none of that.
You had one job: to make them feel like you understand their world better than anyone else who landed in their inbox today. Instead, you told them about yourself.
That’s the hero problem. The recruiter made themselves the main character. But the only story a hiring manager is invested in is their own. If your email doesn’t feature in it, it gets deleted.
Deleted emails don’t reply. They also don’t help your sender reputation.
Your job isn’t to be the hero
Your client is living a story right now. They’ve got a problem. They’ve tried a few things. Some of those things probably looked a lot like you. And they’re waiting, whether they know it or not, for the moment that changes everything.
Your job isn’t to be the hero of that story. Your job is to be the moment everything turns around for them.
The difference sounds small. It changes everything about how you write, and what happens to your domain when you send at scale.
Better engagement isn’t just a vanity metric. It’s the signal that tells Gmail and Microsoft that your emails are wanted. That your domain is worth delivering to. That the people you’re sending to are glad you sent.
In the next post, I walk through exactly how to get there: a six-move framework for writing recruitment emails that make the client the main character, from the first line to the close.
What This Means for Recruiters
The link between email writing and email deliverability is something most recruiters don’t think about until something goes visibly wrong: replies drying up, candidates saying they didn’t get the job alert, clients asking why your email landed in their junk folder.
By that point, the damage to your domain reputation is often months old.
Spec email volume is a normal part of running a recruitment desk. But sending high volumes of low-engagement email from your agency domain is one of the fastest ways to erode the sender reputation that every other email you send, job alerts, interview confirmations, client updates, depends on.
The fix isn’t to stop sending spec emails. It’s to send better ones. Ones that get opened because they’re relevant. Ones that don’t get marked as spam because they don’t feel like spam.
That’s what the hero framework is actually for.
Frequently Asked Questions
Do speculative recruitment emails still work?
Yes, in the right market, with the right candidate and a well-targeted client list. They’ve always had modest reply rates, and that’s fine. The issue isn’t whether they work; it’s the cumulative deliverability cost of sending them at volume with low engagement, which is a newer problem than most recruiters realise.
How do low email open rates affect my domain reputation?
Inbox providers like Gmail and Microsoft use engagement signals, including opens, deletions, and spam reports, to assess whether a sending domain is trustworthy. A domain that consistently generates ignored or spam-flagged emails gets filtered more aggressively over time, which affects every email you send, not just spec outreach.
How do I know if my domain reputation has already been affected?
The clearest signs are declining open rates, emails landing in junk folders, and candidates or clients reporting they didn’t receive something you sent. A domain health check will give you a more precise picture, including whether your authentication setup is compounding the problem.
What’s the quickest change I can make to improve spec email engagement?
Read your last five outbound emails and count how many sentences begin with “I” or “We.” If most do, your email is about you, and it needs to be about them. Starting with something true and specific about the hiring manager’s world, rather than your candidate’s availability, is the single highest-leverage change you can make.
