WhatsApp vs email in recruiting: why candidates go silent

A candidate finds your opening, likes it, and fills in the form. The company sends a confirmation email with the next steps. That email never gets opened.

Not because the job stopped mattering. Almost nobody watches their inbox the way they watch WhatsApp anymore, and the message they would have opened, the one in the chat they hold all day, never reached them.

That is where a lot of hiring processes die. Not at the interview, not at the offer. In a confirmation email that went unread.

The numbers aren’t close

The gap between the two channels is not a matter of degree. The figures the industry works with (WhatsApp Business and the messaging providers) put WhatsApp open rates well above 90%, and cite as high as 98%, with most messages read within minutes. These are industry estimates rather than a closed study, but even the conservative end leaves email far behind.

Email, meanwhile, flatters itself. Mailchimp’s benchmarks put the average open rate around 35%, and that number has been inflating for years: since Apple Mail started opening emails automatically to protect privacy, a large share of those “opens” are a system opening the mail on the user’s behalf, not a real read. The figure a recruiter sees in the dashboard says more than it seems and less than it promises.

Put plainly: the WhatsApp message almost always gets seen, and almost always soon. The email often goes unopened, and when the dashboard says otherwise, frequently nobody actually read it.

In a normal process, you can paper over that difference by chasing. In a high-volume one, you cannot.

Where it becomes decisive: high volume

Think about who fills the roles that move the labor market: logistics, hospitality, retail, customer service. Frontline profiles job-hunting from their phone, often without an active work email or the habit of checking an inbox several times a day.

For that candidate, email is invisible. You write to schedule the interview and get no reply, not because they said no but because they never saw it. The process drags, the role stays open, and meanwhile they take the first job that answered fast, which was almost never you.

When you are screening hundreds of candidates per role, those silent drop-offs are not stray cases. They are the biggest leak in the funnel, and the cheapest one to plug: write where the candidate already is.

How Hirevoice solves it

Hirevoice reaches the candidate over WhatsApp from start to finish. It schedules the interview there, sends the reminder there, and runs the conversation there, without depending on anyone checking their email. The channel stops being the bottleneck and becomes what it should have been all along: the place where the candidate replies.

There is no open-rate trick to it. You drop the mailbox the candidate does not open and move to the chat they already have open, which also happens to be the channel most US-built tools still ignore. In processes measured in days and hundreds of applications, that single decision is often the difference between filling the role and posting it again.

If your processes keep stalling on “we wrote and got no reply,” the problem probably is not the candidate. It is the channel.
