How to build a multi-channel prospecting sequence

Why one channel plateaus

Each channel reaches only part of a list. A call finds the person who answers an unknown number, email the person who reads their inbox, mail the person who opens the post. Repeating one channel mostly repeats the same misses.

Repetition also matters. A sales-software vendor survey of 500 revenue professionals reported an average of 4.81 touches before a prospect responded (vendor-reported, via a vendor cadence guide). A sequence spends those touches on different channels so each record gets several chances to land.

Which channels need consent

Build the sequence from the consent you hold, not from the channels you like. Mail needs none. Live calls need a Do Not Call scrub. Email needs CAN-SPAM compliance. Text and ringless voicemail need prior express written consent. A record with no phone consent gets mail, calls to scrubbed numbers, and email only.

Channel	What it needs	Source
Direct mail	No consent. No federal registry.	See direct mail prospecting
Live call, manual dial	Number not on the national registry unless you have a written agreement or an established business relationship. Registry copy no more than 31 days old. Calls only between 8 a.m. and 9 p.m. in the called person's local time.	16 CFR 310.4
Email	Accurate headers, non-deceptive subject, ad disclosure, physical address, working opt-out honored within 10 business days. No B2B exception.	FTC CAN-SPAM guide
Text (autodialed or prerecorded)	Prior express written consent for telemarketing to wireless numbers.	47 CFR 64.1200(a)(2)
Ringless voicemail	Treated as a prerecorded call to a wireless number. The FCC ruling released 11/21/2022 says it requires consent.	FCC 22-85
LinkedIn message, door visit	No federal consent rule on this page's sources. Follow platform terms and local solicitation ordinances.	Platform terms, city code

Most business-to-business calls are exempt from the FTC Telemarketing Sales Rule, including its registry provisions. Calls that sell nondurable office or cleaning supplies, and calls that ask an individual to buy for personal use, are not (FTC Telemarketing Sales Rule guide). Read the cold calling laws summary and the TCPA explained page before you add a phone touch.

Cadence one: property owners, 30 days

For a property-owner list the order is mail, call, mail, call, then a door visit or a last mailer. Mail goes first because it needs no consent and gives the later call something to refer to. The call lands after the piece has had time to arrive. Details for each channel are in cold calling, door knocking and retargeting from lists.

• Day 0Mail 1. Postcard, one offer, a phone number used only for this touch.
• Day 5Call 1. Scrubbed numbers only, 8 a.m. to 9 p.m. local time. Reference the postcard.
• Day 12Mail 2. Letter or second postcard with a different headline and a different tracking number.
• Day 19Call 2. Different time of day from call 1. Leave one short voicemail, live-dialed.
• Day 28Door visit if the property is within your territory, otherwise Mail 3 as a final ask.

Cadence two: business prospects, 30 days

For a business list the order is email, call, email, LinkedIn, call. Email opens because it is cheap and leaves a record. The call follows within a few days. Vendor guides recommend more touches over fewer days (table below); this version suits a small team and a list you plan to reuse. See cold email for the sending rules.

• Day 1Email 1. Two sentences, one reason you wrote, one question.
• Day 4Call 1. Business line first. Scrub any mobile number against the registry before dialing it.
• Day 9Email 2. New angle, not a "just checking in".
• Day 15LinkedIn connection request with a short note, no pitch.
• Day 22Call 2, then a closing email the same day. State that this is the last message.

Text and ringless voicemail are left out of both rails on purpose. Add them only for records with a signed opt-in. The text prospecting page covers that case.

Touch counts and spacing

Published touch data comes from vendors, not regulators or audits. Test every figure below against your own list.

Measure	Figure	Source and label
Average touches to get a response	4.81, 500 respondents	Sales-software vendor survey, reported in a vendor guide. Vendor-reported.
Cold outbound touches	8 to 16	Vendor guide synthesis of practitioner advice. Vendor-reported.
Cold outbound span	17 to 21 days	Vendor guide, citing one practitioner. Vendor-reported.
Warm inbound touches	5 to 12 over 7 to 10 days	Vendor guide, citing another vendor's data. Vendor-reported.
Cold email reply rate	0.45% of emails sent, 7,530,489 emails, 2025	Outbound agency study. Vendor study. The denominator is emails sent, not people.

Never send two touches to one person on the same day. Change the channel before you change the message.

Cost per 1,000 records, worked

This example prices the property-owner cadence for 1,000 records. All three mail pieces are priced as postcards at the USPS commercial First-Class machinable presorted rate of $0.501, effective 10/04/2026. A list barcoded and sorted to automation 5-digit pays $0.453 instead (see direct mail prospecting). Every other input is an assumption.

Line	Arithmetic	Cost
List, 1,000 records	Assumed $0.10 per record, your quote	$100
Three postcards, postage	3 x 1,000 x $0.501	$1,503
Three postcards, print	3 x 1,000 x $0.25 assumed	$750
Calls	60% have a scrubbed phone = 600 records, 2 rounds = 1,200 dials. At 40 dials an hour, 30 hours. 30 x $25 assumed	$750
Door visit	Skipped in this example	$0
Total	100 + 1,503 + 750 + 750	$3,103

That is $3.10 per record worked. Cost per lead is the total divided by leads:

• 10 leads (1% of 1,000): $3,103 / 10 = $310.30 per lead.
• 20 leads (2% of 1,000): $3,103 / 20 = $155.15 per lead.

Compare that to what a deal pays. If a deal pays an assumed $4,000 and an assumed 1 lead in 10 closes, break-even is $400 per lead. The 1% case clears it at $310.30, and so does the 2% case. Run your own numbers before scaling.

Tracking: one number per channel

Give each channel its own tracking phone number and reply code, so a caller tells you which touch worked without being asked.

Channel	Tracking number or code	Reply code example
Postcard 1	Number A	Say "blue card"
Letter or Mail 2	Number B	Say "letter"
Outbound call	Caller ID number C	Callback to C
Email	Number D or a reply keyword	Reply "YES"

Log every touch with the date, channel and outcome. Log a stop request on any channel against the record, not against the channel, and suppress the record everywhere.

What good numbers look like

These bands are planning targets from your own break-even math, not published norms.

Measure	How to calculate	Healthy sign
Delivery	Pieces delivered / pieces mailed	Above 95% after NCOA and address standardization
Reach	Records with at least one live contact / records worked	Rises across the 30 days
Response	Responses / records worked	Above your break-even rate from the cost example
Cost per lead	Total cost / leads	Below the amount one deal pays divided by your close rate
Opt-outs	Stop requests / records worked	Near zero, and every one honored

If email replies are far below 0.45% of sent messages, fix the list and the subject line before adding touches.

Compliance notes

Check these before day 0, and re-check before each phone touch:

1. Scrub phone numbers against the national registry and your internal stop list. The registry copy must be no more than 31 days old at call time (16 CFR 310.4(b)(3)(iv)).
2. Call only between 8 a.m. and 9 p.m. in the called person's local time (16 CFR 310.4(c); 47 CFR 64.1200(c)(1)).
3. Email must carry a physical postal address and a working opt-out, honored within 10 business days. Penalty is up to $53,088 per email (FTC).
4. Texts and ringless voicemail need prior express written consent. Keep the signed record. The Telemarketing Sales Rule requires telemarketing records to be kept for two years (FTC).
5. Honor a revocation of consent in any reasonable form within 10 business days (47 CFR 64.1200(a)(10)).
6. A stop on one channel is a stop on all channels for that record.

Questions people ask

Q01How many touches does it take to reach a prospect?

A sales-software vendor survey of 500 revenue professionals reported an average of 4.81 touches to get a response, and vendor guides recommend 8 to 16 touches for cold outbound. Treat both as vendor-reported. Plan 5 to 8 touches in 30 days, then judge by your own reply data.

Q02Should I use the same message on every channel?

Keep one offer and one ask, but change the wording. A postcard has room for one sentence, a call opener has ten seconds, and an email can carry a short reason. Repeating the same words on every touch reads as automation and gives people nothing new.

Q03Can I text a prospect after they ignore my mail and calls?

Only with prior express written consent for that seller. An unanswered call or mail piece is not consent. Without a signed opt-in, the next touch should be another mail piece, call or email.

Q04When should I stop contacting a record?

Stop on a reply of any kind, a stop request on any channel, or the end of the sequence. Honor a revoked consent within 10 business days at the latest, and apply the stop to every channel, not only the one used.
