How to build a cold email sequence that gets replies

Most advice on sequences ends at the last email. That's the part you control least. The meeting gets won or lost after a prospect writes back, when "sure, send me times" sits in a shared inbox under a pile of auto-replies.

This guide walks through the whole thing: how many emails to send, how far apart, what each one says, a five-email template you can copy, and what to do with each kind of reply once your sequence stops.

What you need before you start

What is a cold email sequence?

A cold email sequence is a series of emails sent automatically to someone who hasn't heard from you before, where each step goes out only if they haven't replied yet. The first email makes the pitch. The follow ups give the prospect more reasons and more chances to answer.

Two terms get mixed up with it. Email cadence is the timing inside the sequence: how many emails and how many days apart. A follow up sequence is everything after the first email. Both are parts of one cold email sequence, so you'll see all three phrases used for the same setup.

Step 1. Pick one offer and one segment

One sequence should speak to one kind of buyer about one problem. When you load founders, heads of sales and marketing managers into the same campaign, the opener has to stay vague enough to fit all three, and every follow up inherits that vagueness.

Write the segment down as a sentence before you write any copy: "Heads of operations at freight brokers with 20 to 200 staff who posted a dispatcher job this month." Then write the offer in one line, in the buyer's terms, and the single proof point you can stand behind.

• Who: one role at one type of company, at one size band
• Why now: the trigger you can see from outside (a hire, a launch, a new location)
• Offer: what they get and what it costs them in time to find out more
• Proof: one real result, client or detail you're allowed to share

If you can't fill in "why now", the list is too broad. Split it and write a second sequence rather than stretching one.

Step 2. Decide length and spacing

Four to five emails is enough for most B2B sequences. Fewer and you stop before a busy prospect gets to your email. More and the later emails start repeating themselves, and repeated pitches are what push people from ignoring you to marking you as spam.

Space them with gaps that widen: two days after the opener, then four, then a week, then a week again. The first follow up arrives while the opener is still near the top of their inbox. The later ones give the prospect room to breathe.

A starting cadence. Count business days if your sequencer skips weekends, and send in the prospect's time zone.

Plan your sending volume around the follow ups too. Instantly's help center recommends about 30 campaign emails a day per sending account, and by default a campaign sends due follow ups before it contacts new leads. A five-step sequence on a full list can use most of a day's capacity on follow ups by week two.

Step 3. Write the opener

The opener carries the whole sequence. Every follow up refers back to it, so it has to make the point clearly enough that "any thoughts on the note below?" makes sense two days later.

Subject line

Two to five plain words that could come from a colleague: "dispatcher hiring", "question about Northline", "freight quotes". Skip the clickbait. You want the subject to match the email, because the follow ups reuse it in the same thread.

Body

Keep it under about 100 words, in four short parts:

1. A first line about them. The trigger from Step 1, stated plainly: "Saw you're hiring two dispatchers in Dallas."
2. The problem it points to. One sentence, in their words.
3. What you do about it, with the proof. One or two sentences, with the one real detail.
4. A question that's easy to answer. "Worth a look?" is easier to say yes to than "Do you have 30 minutes on Thursday?"

Write it as plain text, with no images or attachments, and with at most one link. Sign off with your name and title, not a banner.

Step 4. Write each follow up

Every follow up needs a reason to exist beyond "checking in". Give each one a single job, and write it so it still makes sense if it's the only email the prospect reads.

Email 2: the short bump (Day 3)

Two or three lines in the same thread. Add one detail the opener didn't have, such as a number, a client name or a one-line example, and ask the same question again.

Email 3: proof (Day 7)

Tell a short story about one client like them: where they started, what changed, and how long it took. Use only results you can back up. If you don't have a case yet, explain how the first month works instead.

Email 4: a new angle (Day 14)

Start a new thread with a new subject. Pitch a second problem your offer solves, or offer something useful for free: a short teardown, a benchmark from your own clients, a checklist. Some prospects ignored email 1 because the first problem wasn't theirs.

Email 5: close the loop (Day 21)

Say this is your last note, make the ask small, and give them an easy way out: "Should I close this out, or is someone else on your team the right person?" The second question gives them an easy way to point you to the right person.

Step 5. Set stop rules on reply

A follow up that lands after the prospect has already answered is the fastest way to look automated. Set these rules before you launch, then test them with a reply from your own address.

• Stop on any human reply. In Instantly the setting is "Stop sending emails on reply", under the campaign's Settings, then Advanced settings. It's on by default, but check it, because turning it back on later doesn't stop leads who replied while it was off.
• Decide what an auto-reply does. An out of office reply isn't a no. Instantly has a separate "Stop sending emails on auto-reply" switch, and its out-of-office resume feature, which pauses the lead until their return date, only works with that switch turned off.
• Watch replies from other addresses. When a prospect forwards your email to a colleague, or answers from a personal address, the sequencer may not match the reply to the lead. Instantly's help center says these replies land in an "Others" folder and the follow ups keep going.
• Check follow-up branches. Instantly subsequences triggered by a reply status, such as Interested, keep sending even after the lead replied. That's by design, so make sure the copy fits someone who already answered.
• Stop for good on an unsubscribe or a bounce. Remove the address from every other campaign too, not just this one.

Step 6. Route replies (interested, OOO, referral, not interested)

Once the sequence stops, the reply needs an owner. Replies fall into a handful of types, and each type needs a different next move. Sort them first, then answer, so the "yes, send times" replies don't wait behind a pile of auto-replies.

Interested or meeting requested

Answer with two or three specific times, or a booking link, plus one line that confirms what the call covers. Don't restart the pitch. They already said yes to it.

A question first

"How much is it?" or "Do you work with companies our size?" is a buying signal. Answer the question directly in two or three lines, then ask for the meeting in the same email.

Out of office

Note the return date from the auto-reply and write back a day or two after it, in the same thread, with a short reminder of your first email. Don't send the next sequence step into an empty inbox. Our holiday out of office message examples show what these auto-replies usually say, including the return date and backup contact you can use.

Referral

"Talk to Priya, she runs ops" is a warm intro. Email Priya in a new thread, name the person who pointed you to her in the first line, and keep the original prospect copied only if they offered to make the intro.

Not interested

Thank them in one line, or don't reply at all, and remove them from every active campaign. If they asked to unsubscribe, honor it everywhere you send from.

Revbound does this routing for cold email. It pulls every reply from your sequencers (Instantly, Smartlead, Email Bison, PlusVibe, SendKit and ArcSend) into one inbox and sorts each one with AI: interested, meeting requested, out of office, referral, not interested and so on. The positive-reply responder drafts the answer for you to review, or sends it automatically. It offers times that are actually free on your Cal.com or Google Calendar and books the meeting when the lead says yes. It also writes back to out-of-office leads when they return, contacts the person a referral points to, and keeps following up for about two months. Plans and the free trial are on the Revbound pricing page.

Cold email sequence template (table)

Here's the full five-email template. Use the table to plan, then copy the emails below and swap the brackets for your segment, trigger and proof.

Every step stops for a lead the moment they reply. Replies then go to the routing in Step 6.

Sales cadence vs email sequence

A sales cadence is the full plan of touches a rep makes with one prospect across every channel: emails, phone calls, LinkedIn messages and sometimes texts, with a set order and timing. An email sequence is the email part only. Every email sequence can sit inside a sales cadence, but a cold email sequence on its own is email from start to finish.

Definitions of the two terms as sales teams use them. "Email cadence" is the timing inside an email sequence.

Revbound fits on the email side only: it handles cold email replies and does not send or answer LinkedIn messages, calls or texts.
