The 4-Touch Email Cadence: Why Business Days 0, 3, 10, and 17 Work

JacSend automates a four-touch sequence spaced across business days 0, 3, 10, and 17. Here is the psychology and data behind that cadence - and how to make each touch count.

9 min readUpdated June 2026

Not all follow-up spacing is equal. Too tight feels pushy; too loose loses momentum. JacSend ships with a fixed 4-touch cadence on business days 0, 3, 10, and 17 because that rhythm balances persistence with respect across typical B2B buying cycles.

This article explains each touch, what to say, and how the queue prioritizes these follow-ups before new first-touch outreach.

Overview of the 4-touch cadence

Touch 1 ships on activation (business day 0). Touch 2 follows on business day 3 - early enough to catch people who missed the first email, late enough to avoid same-day stacking. Touch 3 lands on day 10 with a fresh angle or proof. Touch 4 on day 17 is the polite close-the-loop message that often earns a reply.

Business days skip weekends, matching when most B2B recipients read mail. JacSend's cron runs hourly on weekdays to queue the next eligible touch per contact.

Touch 1 (day 0): the initial outreach

Your opener establishes relevance, names a problem or opportunity, and ends with a low-friction ask. JacSend AI drafts this from your campaign brief and contact context. Keep it under 125 words and plain text.

Touch 2 (day 3): the quick bump

Three business days later, send a shorter reply-in-thread note. Restate the core value in one line or ask a yes/no question. Many positive replies happen here because the first email resurfaced in the same thread.

Touch 3 (day 10): add new value

By day 10, introduce something new: a customer result, a relevant article, a product update, or a sharper question about their priorities. Do not repeat touch one verbatim.

Touch 4 (day 17): the break-up email

The final touch grants an easy exit: 'Should I close the loop?' or 'Is this not a priority?' Break-up emails often get the highest response rate because they remove pressure and invite a quick no or a deferred yes.

How JacSend queues the cadence

Follow-ups queue before new outreach. Daily and hourly caps prevent server overload and spam spikes. Default cron sends up to 5 emails total and 1 per campaign per hourly run on weekdays - tune expectations with your SMTP limits.

Frequently asked questions

Can I customize the 4-touch cadence in JacSend?
JacSend uses a fixed business-day schedule (0, 3, 10, 17) to keep the product focused and predictable. Customize copy per touch and campaign, not the spacing, in the current MVP.
Do weekends count toward the cadence?
No. JacSend counts business days only, so sequences pause over weekends and resume on the next weekday.
What if I activate a campaign mid-week?
Day 0 sends when eligible in the queue. Subsequent touches calculate from that anchor on business days 3, 10, and 17.
Are follow-ups sent as replies in the same thread?
Yes. JacSend adds In-Reply-To and References headers on follow-up touches so messages group with your initial email in most inboxes.
How does the cadence interact with plan send limits?
Each touch counts toward your monthly send quota. A full sequence uses up to four sends per contact unless they reply or decline earlier.
