Email sequences and cadences: how to build one

An email sequence is a planned set of messages sent to one person, stopped the moment they reply. Plan three to five steps, a few days apart, where each step adds a new reason to answer. Instantly's 2026 report calls four to seven touches the sweet spot and spaces them three to four days apart. Stop on any reply, and cap the total.

A single email is a bet that your message lands on the right day. A sequence is a plan that gives the same message several chances without repeating itself. This post shows how to build one: what each step does, how long to wait, when to stop and how to read the results. It is written for people who send cold email themselves or set the rules for an agent that does.

Sequence or cadence, what is the difference?

A sequence is the list of messages. A cadence is the rhythm: how many days apart, which weekdays, and which channels. In practice you decide both together, because the content of step three depends on when it arrives. If you want the short definition, see our glossary entry for an email sequence.

How many steps do you need?

Instantly's 2026 benchmark report, which covers platform data for 2025, says 58% of replies come from step one and 42% from follow ups, and calls four to seven touchpoints the sweet spot. The Shelly installer programme shows the effect on one audience: the first email alone drew a 3.3% reply rate, while the sequence reached 13.6%. Three in four replies came only because of a follow up. Read the case study.

More steps do not always help. Each extra message brings a few more replies and a few more refusals. A formal audience, such as compliance officers, tolerates fewer touches than a friendly one. Our post on how many follow ups depends on the relationship gives a way to choose. A safe start is three or four steps; add one only when the last step still draws replies you want.

What goes in each step?

Every step needs its own reason to exist. If you cannot say what a step adds, delete it.

Instantly says the best step two emails feel like replies, not reminders, and that they outperform formal follow ups by about 30%. That is the vendor's own data, so read it as a hint: a step two that starts "One more thought on X" beats one that starts "Following up on my email".

Hotel Pirin used this shape for group sales. The first letter said who the hotel was, made one offer and asked for dates and headcount. Follow up 1 gave a new reason to act now, such as a worked cost for a 20 person offsite. The last note said, in effect, this is my last note on this topic, restated one offer and asked for two facts. The numbers are in the case study, a related party study since the hotel is owned by a Sellinger co-founder.

Which step earns the reply?

The Hotel Pirin letters show a pattern worth knowing.

The first letter found the need. Follow up 1 drew the most replies, but mostly polite ones such as "not now". The last note drew fewer replies and four inquiries, one of which was forwarded inside a company and became a confirmed booking. Seventeen replies forwarded the letter to a colleague. The lesson is to write the last note so that it can be forwarded: it should stand on its own and name one offer. We keep a template for a forwardable last note.

How many days between messages?

Instantly advises three to four days. Sellinger's defaults for email run from one to three days between follow ups, with five follow ups before a lead is treated as exhausted and then a move to WhatsApp. Defaults on LinkedIn start at five days. Every value can be changed per campaign, and a campaign's own settings win over the defaults.

Rules that hold across audiences:

• Do not send two touches on the same day.
• Skip weekends for business audiences.
• Space later steps wider than earlier ones. The fourth message does not need to arrive three days after the third.
• Respect the recipient's time zone. See the best time and day to send cold emails.

When should the sequence stop?

Build the stops in before the sends.

1. On any reply. A refusal, a question, an out of office with a return date and a forward all end the automatic follow ups for that person. Auto replies from helpdesks or no reply senders are not human replies and should be flagged, not answered.
2. On an opt out. STOP or unsubscribe ends everything, permanently, for every channel. In Sellinger the contact goes on the team's suppression list and the platform checks it before every send.
3. On a bounce. A hard bounce ends the sequence for that address.
4. At the cap. After the last step, stop. Do not restart the same person next month with the same text.
5. When you are asked. If a client or colleague says "only one email", check what is already scheduled. A stop rule must reach every queued step.

What does a whole sequence look like on the page?

Here is a four step example for a business owner, with invented details. Replace each part with your own facts.

• Step 1, day 0. "Hi Maria, I saw you opened a second studio in Varna. We help studios fill quiet weekday slots without discounting. Is that a problem for you this season?"
• Step 2, day 4. "One more thought: studios we have seen start with a single off peak class and add a second only if it fills. Would a short note on how that works be useful?"
• Step 3, day 9. "If weekday slots are not your area, who looks after bookings at the studio?"
• Step 4, day 14. "This is my last note on this. If filling weekday slots matters later, reply with the days that are quiet and I will send one idea. Either way, all the best with the new studio."

Notice what each does. Step 2 adds a fact. Step 3 asks for the right person, which turns a no into a forward. Step 4 closes politely and asks for two facts, not a meeting. Nobody is chased, and each message can be read alone.

Can one sequence span channels?

Yes. A LinkedIn invitation, a message and then email are one sequence in three places, and a reply on any of them stops the rest. We show three day by day versions in the LinkedIn then email cadence. The thing to avoid is writing the same text on each channel. Each step should say something new.

How do you review a sequence?

After 100 sends per step, read three things.

• Replies by step. Which step earns replies you want, not just replies.
• Refusals by step. If step four brings mostly unsubscribes, cut it.
• Forwards. A forward is a quiet win. Count it.

Then change one thing at a time. If you change the subject line, the offer and the timing in the same week, you will not know which one mattered. Our post on A/B testing outreach messages covers how to run the test.

A sequence checklist

• [ ] Three to five steps, and each adds something new.
• [ ] Two to four days between early steps, wider later.
• [ ] The last note stands alone and can be forwarded.
• [ ] A reply, an opt out or a bounce ends the sequence.
• [ ] The stop rule reaches every queued step.
• [ ] I review replies and refusals by step after 100 sends.
