After the first send, most of what you should do is check four things at set times and otherwise leave the campaign alone. First-time senders usually do the opposite. They refresh the sent folder every ten minutes, rewrite the subject line at noon, and send twice as many emails the next morning because it "feels slow." Day one is mostly a quiet day with three or four moments that need you.
The example below is made up: Kofi Mensah, who runs Cascade Espresso Service in Portland and repairs commercial espresso machines. He sent step one of a sequence to 30 cafe owners at 9:00 a.m. on a Tuesday, from his own Gmail. The step two follow-up is scheduled for Friday.
The checklist, by the clock
| When | Check | If it goes wrong |
|---|---|---|
| 9:00 to 9:15 | Open two sent emails. Right name, signature, postal address, opt-out line? | Pause the rest and fix the template |
| 10:00 | Count bounce notices in the inbox | 4 or more of 30: stop sending and check the list |
| 1:00 p.m. | Sort auto-replies from real replies | Note return dates. Do not answer a robot |
| 5:00 p.m. | Answer every human reply | Reply within the hour, using the wording below |
| Any time | Opt-out requests | Remove the same day, confirm in one line |
| Wed 9:00 | The ten-minute day-two review | Decide: same volume, or fix first |
Hour 1: bounces tell you about the list
Within a few minutes of a send, bounce notices start arriving in the same inbox, titled something like "Delivery Status Notification (Failure)." A hard bounce means the address does not exist or the domain does not accept mail. A soft bounce means a full mailbox or a temporary server problem.
On 30 emails a single bounce is 3 percent, so the percentages swing wildly. One or two hard bounces is a cleanup chore, not a crisis. Kofi got two: one cafe had closed, and one address had a typo. He deleted both from his list and did not resend. Four or more out of 30 (about 13 percent) is a signal that the list is old or badly sourced, and sending more mail to it damages your own address's reputation. If that happens, stop the sequence, verify the addresses with a checker or find them again, and start over with a clean list. The numbers and thresholds are explained in cold email bounce rate.
At 9:00 Kofi also opened two of his own sent emails. A cold email to a business needs your real name, an accurate subject line, a postal address and a working way to opt out (that is the CAN-SPAM rule in the US). It is annoying to find a missing address after 30 emails have gone. It is much less annoying after two.
Hours 2 to 6: auto-replies are not replies
By lunch, three auto-replies had arrived: two out-of-office messages and one "this mailbox is no longer monitored." Kofi's rules for these:
- Out of office with a return date: write the date on the contact. Do not reply. Make sure step two will go out after they are back, not while they are away.
- "Left the company" or a forwarding address: find the new owner and add that person as a fresh contact.
- A ticket number or "we received your message": ignore it. It is a system, not a reader.
More on this is in cold email auto-replies and out of office. The one thing not to do is reply to an auto-reply. It makes you look like you are not reading anything.
Hours 6 to 24: the first real replies
Kofi got two human replies by 5 p.m. The first: "Interesting. Our La Marzocco has been leaking from the group head. Can you come Thursday?" The second: "Not interested, thanks." The first one is the reason the campaign exists, and it should get an answer within the hour. He wrote:
Thanks, Priya. Group head leaks are usually a gasket or a valve, and most visits take under an hour. I can come Thursday at 9:00 or 2:30. Which is better? And what's the model and roughly how old is it?
For the second, he wrote one line: "Understood, thanks for letting me know. I won't write again." He then took the person off the list, which stops the Friday follow-up. If you want the fuller handling of both kinds, a reply came back, now what and how to respond to a not-interested cold email reply go through them, and the six-reply router covers the other types.
An opt-out is a result, not a failure
A third reply that evening read: "Please remove me from your list." Under CAN-SPAM you have up to 10 business days to honor that, but do it that day. Take the address off every list and sequence you have. Reply once, "Done. You won't hear from me again," and do not add a sales sentence. Keep a note somewhere permanent so a future campaign never reaches that person. An opt-out in the first 30 emails is not unusual and not a sign the email is bad.
The three things to leave alone
The copy. One day and 30 emails cannot tell you whether the subject line works. Changing it at noon means you will never know what produced the replies you got. Wait for at least 100 sends before rewriting.
The volume. If day one felt slow, the temptation is to send 100 on day two. A new sending pattern from your Gmail is exactly the kind of jump that looks suspicious. Keep it at the same modest number for the first week, and add gradually.
The open-rate number. Many email clients preload images, so open counts can be inflated by machines. Replies are the number that matters. If you see 14 opens and no replies, that is normal for day one.
The day-two review, in ten minutes
Wednesday morning, fill in five numbers for yesterday: sent (30), hard bounces (2), auto-replies (3), human replies (3, of which one interested, one no, one opt-out), and meetings or visits asked for (1). Then decide. Two or fewer hard bounces: delete them and keep going at the same volume. One interested reply out of 30 is a fine start for a first campaign, and zero after one day is not a verdict, since many replies come on day two or three. If bounces were high, or the sent emails looked wrong when you opened them, stop and repair before the Friday follow-up goes out.
If you would rather not watch the inbox on day one, Rocketship's email worker sends from your own Gmail at a modest pace, suppresses bounces so they are not retried, reads the replies as they arrive, and answers the interested ones. Who does what is on the AI workers page, and how to stop follow-ups the moment someone replies shows how to test that part before you start.
Rocketship finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own. Plans that get you customers start at $24.99 a month (Launch), and both Launch and Frontier start with a 7-day free trial, card required.
