B2B cold email templates we actually send (and the rules behind them)

Sunny Ray · Sep 18, 2026 · 6 min read

The best B2B cold email template is a short, plain-text invitation: a few lines that say who you are, why you picked this person, and invite them to be a guest on your show, with no links, no images and no pitch. Follow it with two short follow-ups, then stop. Below are the actual templates we use for buyers, investors and partners, plus the rules behind them, because the rules matter more than the words.

I showed our setup to a founder on a call this morning. We ran 250 mailboxes last week and we're scaling to 2,500. Our campaigns run about 4,000 leads each, pulled from Apollo, on three-touch sequences with no URLs or images. Yesterday alone we had 65 replies come in from CEOs, founders and Series A and B investors. The copy principle behind all of it fits in one line: hey, you want to come on my show?

The rules before the templates

Copy a template without the rules and it won't work. These are the ones we hold to.

• Plain text only. No images, no logos, no emoji. We give the same advice for newsletters sent through cold infrastructure: images and emoji add spam risk.
• No links in the first email. Not your website, not your calendar.
• Short. Instantly recommends under 80 words, and we stay well under that.
• One ask, and it's a give.
• Three touches: the first email and two follow-ups. Then we stop.
• Separate sending domains. Your main domain never sends.

On the sequence length, we're in line with the big datasets. Smartlead's analysis of more than 850 million emails sent from January to June 2026 found the median sequence runs three emails.

Template 1: the show invitation (buyers)

Subject: guest on [show name]?

Hi [first name], I host [show name], conversations with [role]s on how they're handling [problem]. The way you've [specific thing about their work] is exactly what our listeners want to hear about. Would you come on as a guest? Thirty minutes, recorded, and you get the episode and clips to share.

Why it works: it's about them, it's specific, and the ask is a gift. People might not care about your company, but they care about their own story. The sales conversation comes later, in the pre-interview and the debrief, once they've said yes to you.

Template 2: the investor invitation

Subject: [first name], on [show name]

Hi [first name], I host [show name], where I talk with investors about how they're thinking about [your sector] right now. Your view on [a theme from their portfolio or writing] would make a great episode. Would you join me as a guest? Half an hour, and we'll send you the clips.

Why it works: it flips the power dynamic. Instead of asking an investor for money, you're offering them a platform. They prepare to impress you. When the subject of your company comes up, and it will, you're talking as peers. We've also used the invitation as the fourth email in an existing investor sequence, so an investor who ignored a direct ask gets a different kind of message.

Template 3: the partner invitation

Subject: [show name] x [their company]

Hi [first name], I host [show name] for [shared audience]. Your customers and ours overlap a lot, and I'd love to have you on to talk about [their expertise]. Would you be up for it?

Why it works: partnerships tend to start as good conversations. An episode is a good conversation with a recording attached, and it tells you within 30 minutes whether there's a fit.

Follow-ups 2 and 3

Follow-up 2, a few days later:

Hi [first name], wanted to bring this back up. We're booking guests for the next few weeks and I think your take on [topic] would land well with our audience. Interested?

Follow-up 3, a few days after that:

Hi [first name], last note from me on this. If the timing's off, no problem at all. If you'd like to come on later in the year, just reply and I'll keep a spot open.

Then stop. The third email closes the loop politely, and plenty of replies come from it, because it's easy to answer.

Templates that stopped working

Some templates still circulate that I'd retire.

• The feature list. "We help companies like yours 3x pipeline with our AI-powered platform." Every buyer has read it a hundred times.
• The calendar grab. "Here's my Calendly, grab 15 minutes." It asks for time before giving anything, and the link hurts delivery.
• The fake reply. "Re: our conversation" when there was no conversation. It's dishonest, and the subject line has to reflect the content anyway.
• The guilt bump. "Bumping this to the top of your inbox." It says nothing new.

And one nuance: the invitation doesn't fit every audience. On a client call in early September we were planning a campaign to a large list of HR leaders. Our advice was not to use the show invitation there. What works better with HR is an opinion-based report angle, something like "How is HR changing in the AI era?" The invitation fits owners and CEOs best. Match the offer to the person.

Template 4: replying to the yes

The reply to an interested guest matters as much as the first email. Keep it short and get them booked.

Hi [first name], great to hear. Here's the link to grab a time for a short pre-interview: [link]. It's 15 minutes so we can plan the episode around what you want to talk about. Looking forward to it.

Now the link belongs, because they asked for it. Two things make this work. Speed: answer within hours, not days. And the right link: the pre-interview booking for your show, with a few questions on the form so you know who you're meeting. In our system every reply lands in one inbox with a draft like this already written in your voice and the right link for your show. You approve it with a swipe.

How to use these templates

Treat them as a shape, not a script. The brackets are where the work is. If you can't fill [specific thing about their work] with something true and specific for each person, your list is too broad.

Write five versions, read them out loud, and cut anything you wouldn't say to that person's face. Then test one change at a time: the subject, or the opener, or the offer, not all three.

For context, Instantly's 2026 benchmark puts the average cold email reply rate at 3.43% and the top quartile at 5.5% or more. If you're well under average after a few hundred sends, change the offer before you change the words.

If you'd rather not write any of this, gtm showrunner writes every invitation in your voice and waits for your approval before anything goes out. You can get invitations written for your buyers.
