“…emails with no subject line were opened 8% more than those with a subject line,” according to “The one sales email subject line you’ve never thought to try.” That’s a provocative statistic offered by Anum Hussain of HubSpot, a respected provider of content marketing software. Reading that statistic might make you wonder if you should start sending emails without subject lines.
“No!” That’s what I screamed when I read the introduction to Hussain’s post. Emails without a subject line scream that they are spam. I typically delete no-subject-line emails without opening them or even looking at the preview text. I don’t want my computers contaminated by their malware and ridiculous advertisements. I am fussy about email subject lines. I’ve even rejected a legitimate email sent by my husband.
However, even Hussain admits that you shouldn’t start omitting subject lines in every email.
That said, my personal opinion is that it’s highly unlikely that a cold email or first-time prospecting email will be opened with no subject line included. But once you’ve made a connection and are in a cadence of communication … the subject line may become unnecessary.
I agree that I may open an email from someone I know when there’s no subject line. But I won’t like it. I’ll feel annoyed that the writer didn’t value me enough to write an informative subject line.
My opinion? You should never send an email without a well crafted subject line.
