For most founder-led B2B companies, cold email should go out under the founder's name first. Keep it there while the message is still being proven.
Then move to a sales rep, sending under their own name, once three things are true.
The rep's public profile holds up when a prospect looks them up. The rep has new mailboxes that are set up and warmed. And there is a message that already gets replies to hand over.
The title in the signature matters less than what a stranger sees when they look up the person who sent it.
A founder with an empty profile can lose to a rep whose profile explains the offer and shows real proof. A shared sales@ address gives the prospect nobody to look up at all.
The sender rules quoted here were checked in September 2026.
Why the name on the email carries so much weight
In a March 2025 post I put it plainly: "the message alone isn't what gets you responses. It's who is sending it."
The reason is what happens after your email lands. As I wrote in February 2026: "In B2B, nobody buys from an email. They buy after they audit you."
A few lines get read, then the prospect looks the name up. Profile, website, maybe a video, maybe a case study. What they find there decides the reply more than your second paragraph does.
So "founder or rep" is really a question about which person has more checkable proof behind their name.
A polished message from someone who looks like nobody loses to a plain one from someone who clearly knows the field. Better copy will not rescue a weak sender, and neither will a cleverer subject line.
The March 2025 post had the other half of it: "If a well-known industry expert messages you, you pay attention." Your job is to make whoever sends look like that person to the buyer, in the first minute of checking.
My own number on this, a single email earning a 2% reply rate in one company's hands and 7.5% in another's, is in the post on why reply rates follow the sender, along with the checks to run on your own profile.
Smirnov Consulting Group is a Prague-based B2B outbound lead generation agency that runs cold email and LinkedIn campaigns for founder-led B2B companies and books qualified sales calls. With a new client, the profile of whoever sends is usually the first thing my team rebuilds.
What the "email the CEO" data actually measures
Search this question and the studies that come up measure the person receiving the email, not the person sending it.
Gong analyzed more than 1 million executive sales cycles and reported in January 2026 that C-level executives were 30.2% less likely than non-executives to answer a cold email.
Gong sells sales software, so read it as vendor research, though it states its sample.
An outbound agency looked at about a million cold emails it had sent itself between April and October 2025, and its numbers lean the other way.
In that data, 0.27% of C-level contacts sent a positive reply, against 0.088% of directors, about three times the rate.
The two compare different groups and different replies: executives against all non-executives and any reply in Gong's case, executives against directors and positive replies only in the agency's.
The agency's figures are self-published by a company that sells cold email, so treat them as vendor data too.
Both studies answer "who should I write to?" Neither one compares who is doing the writing. Use them to choose your targets, and the rules below to choose your sender.
Founder or rep: the decision by stage
| Stage | Who sends | Why | Move on when |
|---|---|---|---|
| Offer not proven, no sales hire yet | The founder, writing each email personally from a named mailbox | The founder knows what annoys the buyer and hears every objection first-hand | One message keeps earning real replies and at least one call has gone somewhere |
| Message works, founder short on hours | Still the founder's name, with someone else running the setup and sorting replies | The proof sits behind the founder, and replies need fast, informed answers | A rep exists who can take the calls, and their profile has been rebuilt |
| Scaling with reps | Each rep under their own real name, with their own mailboxes, profile and territory | One founder's profile and a few mailboxes cannot carry the volume most growth plans need | No next stage. Every new sender gets the same setup before their first send |
Three rules decide which row you are in.
The stronger public proof sends. If the founder's LinkedIn is a ghost town and the rep's profile has been rebuilt around the problem you solve, the founder's seniority will not make up the difference. Fix the founder's profile or let the rep lead.
Capacity decides when the name moves. Email volume can grow under one name. In the sending setup I use, one real client month averaged about 25 emails per mailbox per day, and the total came from having enough mailboxes, with no single one pushed harder.
What does not multiply is the person. The same post puts the planning ceiling for one LinkedIn profile at 2,800 or so people a month. Every reply and every call under the founder's name also needs the founder's time. When those run out, the next sender is a new person with their own profile and accounts.
The name on the email is the person on the call. A rep writing as the founder, or an invented persona, turns into a problem the moment the prospect joins a call and meets someone else. The sender rules in the questions at the end point the same way.
Fix the profile first. Then move the name.
Test the switch before you make it
The first batch should come from the founder. Around fifty emails, each written for the person receiving it. That is far too few for a trustworthy percentage, and that is fine.
What you are collecting is the objections in the buyer's own words, and the lines they repeat back to you. That is exactly what you hand to the rep later.
Then run a small two-sender test before the name moves for good.
-
Build the rep's side first. Rebuild their LinkedIn profile so it explains what you solve and shows proof. Set up new mailboxes with SPF, DKIM and DMARC, and let them warm up for 10 to 14 days at minimum before real sends.
-
Split the list. Same message, same kind of company, two separate slices of the list, one per sender. Nobody on the list hears from both.
-
Run both slices in the same weeks. Same size, same send times, same follow-ups. The slices are small, so a gap of one or two replies means nothing on its own.
-
Read the replies, not only the count. First rule out the mailboxes. The rep's are newer, so compare bounces and check that replies are arriving on both sides at all.
If both slices land equally, look at what people ask. Replies that question who the rep is, or a slice that goes quiet while the founder's keeps answering, point at the rep's profile and proof, because the message was the same on both sides.
-
Decide. If the rep's replies look like the founder's, hand the name over for new prospects. If not, fix the rep's profile and run the test again, and keep the founder on the accounts that matter most in the meantime.
A few weeks of testing is cheaper than finding out from a quiet pipeline whether the proof travels with the new name.
What to hand over when the sender changes
Two things go missing when a new name starts sending: history and context. This checklist covers both.
-
Mailboxes ready before day one. Google requires everyone sending to Gmail accounts to set up SPF or DKIM, and bulk senders of 5,000+ messages a day to add DMARC with an aligned From domain (Google sender guidelines, checked September 2026).
-
A profile that survives the check. If you ran the test above, the rep's profile is already rebuilt.
The checking does not stop once a call is booked either. I put it this way in my piece on booked calls and no-shows: "Your rep is being audited too, in the gap between the booking and the meeting."
-
The words that already worked. Hand over the messages that pulled replies, the objections exactly as buyers phrased them, the list criteria and the deals you will not chase. Without that, the rep starts at message one knowing less than you did.
-
Separate territories. Founder and rep never write to the same person, and two reps never share a company. Each sender works from their own profile, not the founder's login, and the territory split between sending profiles shows how to divide the list by segment, country or named accounts.
-
A rule for open threads. Decide before the switch who owns conversations already running. Either they stay with whoever started them, or the founder introduces the rep inside that same thread, so no prospect gets a reply from a stranger.
-
An honest From line. The display name and address show the real person sending. The legal side is in the questions at the end.
The rest of the proof stays where it was. The website, the case studies and the founder's profile are still what a curious prospect finds after clicking through, and the rep's email can point at them.
Questions founders ask about the sender
Can I send cold email from my personal Gmail address?
Better not. Use a named address on a company domain, with SPF, DKIM and DMARC in place and the mailbox warmed before real volume.
On a personal Gmail account you do not control the domain's authentication records, and if the account gets flagged, the inbox you use for everything else goes with it.
Should a sales rep sign cold emails with the founder's name?
Generally no, for two reasons. The first is practical: the prospect eventually meets the rep, and the name on the call no longer matches the name on the email.
The second is the rules. Google's sender guidelines say display names and headers should accurately represent the sender identity.
In the US, CAN-SPAM also requires the From and Reply-To to be accurate and to identify whoever started the message, whether a person or a business. This is not legal advice.
Does switching the sender reset my reply rate?
It can. A new mailbox starts with no sending history, so it needs its own setup and warm-up before it can carry volume. Prospects also see a new name and check that person from scratch.
That is why the switch goes through a split test on part of the list first, and why open threads get a clear owner.
Can an agency send cold email under the founder's name?
Only with the founder's permission, and with messages that honestly show who they come from. The founder should then also be the person the prospect meets on the call.
Google says not to impersonate senders without permission. The UK regulator's guidance rules out hiding or disguising who is sending.
Under CAN-SPAM you also cannot hand your legal responsibility to the agency you hire.
Settle three questions with any agency before you sign: who writes the messages, who answers the replies, and who owns the sending domains. The questions I would ask a lead gen agency cover the first two in detail. This is not legal advice.
