Sequence cadence

# Sequence cadence

Sequence cadence is the timing structure of an outbound campaign, how many touches, on which channels, spaced over what window. It is the part of outbound where the operator decides not just what to say but when, and the right answer is rarely what the team intuitively picks at the start. Most operators under-touch in their first campaign and over-correct in their second.

The standard B2B cold sequence in 2026 runs five to seven touches over three to four weeks, mixing email and LinkedIn, with a final breakup message that explicitly closes the loop. Single-touch campaigns under-perform badly because most positive reply rates are accumulated in touches three and four, not touch one. The first message is mostly a probe, the recipient is busy, the message lands during a meeting, and they triage it without acting. The second and third messages are where engagement compounds.

Why it matters

Cadence is one of the few outbound levers that is essentially free to adjust. The list is fixed by the ICP. The message is fixed by the team's writing capacity. The sender, the domain pool, and the deliverability work are all expensive to change. Cadence is a configuration choice. Getting it right or wrong shifts the campaign's reply rate by a meaningful amount with no incremental cost.

The mechanics behind the numbers are well-understood. A busy buyer reads their inbox in triage mode and acts only on the most pressing items. A cold message rarely qualifies as urgent. They mean to come back to it. They forget. A second message four days later catches them in a different state of attention. A third creates the impression that this sender is serious enough to follow up. Each touch is a fresh attempt to catch the prospect in a moment where they have the bandwidth to respond.

Cadence also signals professionalism. A single message followed by silence reads as a casual ask. Five well-timed messages over three weeks read as a sustained interest. The latter converts better in higher-trust buyer segments. The former works fine for lower-trust transactional sales but is rarely the right pattern for B2B.

The risk is that more touches also produce more negative replies and unsubscribes. The breakup message should be designed to close the loop politely. A long sequence that does not include a clean exit will leak negative reply rate and damage sender reputation.

Common pitfalls

The first is using the same message structure on every touch. Touch one might be a short value-prop. Touch three should reference touch one without quoting it. Touch five can be a different angle. Touch seven should be the breakup. Repeating the same template five times annoys the prospect and trains the spam filter.

The second is mis-pacing the intervals. A four-touch sequence that fires every other weekday is hitting the same person five times in two weeks. Most buyers tune out after the second hit in a tight window. The right pattern is increasing intervals, touch 1 to 2 in two days, 2 to 3 in three days, 3 to 4 in four days, etc. Or a flat 3-4 day gap with a longer final gap before the breakup.

The third is ignoring channel mix. Email-only sequences leave a lot of conversion on the table for senior buyer segments where LinkedIn is the preferred medium. The reverse is also true, LinkedIn-only sequences cap at low daily volume and miss inbox-only buyers. A mixed sequence with email touches at 1, 3, 5, 7 and LinkedIn at 2, 4, 6 is a workable default.

The fourth is failing to stop on reply. A prospect who replied to touch two should not receive touches three, four, five. Most senders handle this correctly but mis-configured sequences still send into a live conversation, which is the fastest way to lose a deal that was about to happen.

How it shows up in agent-driven workflows

In Coil specifically, sequence cadence is encoded as a structured artifact the agent reads rather than as free-form prose in a prompt. The user defines a cadence template once, touch one is email, touch two is LinkedIn three days later, etc., and attaches it to a campaign. The agent enforces the structure across hundreds or thousands of prospects without forgetting any individual touch.

The interesting work happens around exceptions. A prospect who opens touch one but does not reply gets a slightly different touch two than one who did not open. A prospect who replied with an out-of-office gets re-engaged after the OOO date. A prospect who clicked a link gets a different follow-up than one who did not. These rules can be encoded as automations and run by the agent.

The pattern that does not work is letting the agent improvise cadence per prospect. The math does not stay coherent. The right division is structured cadence with structured exceptions, both authored by the human, executed by the agent at scale.

The user reviews drafts and approves sends. The agent handles the scheduling, the channel switching, and the reply-driven branching. The agent-driven outbound loop closes around this division of labor.

Cold outreach is the activity cadence governs. The same message at different cadences produces very different results.

Reply rate is the metric cadence moves most directly. A bad cadence caps it. A good one releases the upside the list and message provide.

Deliverability constrains cadence, too-aggressive intervals from a single mailbox trigger provider filters before the prospect even sees the message.

Email warmup determines the cadence ceiling for a new sending domain. New domains cannot sustain the volume a mature one can.
