A win back campaign for a B2B supplier is four emails and one phone call, sent over about three weeks to accounts that used to order and stopped. It starts in your order history, not in your email tool, and it is measured in reorders, not opens.
Most guides on the first page of Google are written for online stores: a "we miss you" email and a discount code. A distributor or manufacturer has a different problem. The buyer who stopped ordering may have left the company, moved the part to a cheaper supplier, or finished the project that needed you. A coupon fixes none of that.
This guide covers the B2B version, from the order export to the reorder count. Winning buyers who have never ordered from you is a different job, covered in how SEO works for manufacturers.
Key takeaways
- Start from orders, not opens. An account is dormant when its time since the last order is more than twice its usual gap between orders.
- Clean before you send. Buyers change jobs, and bounces and spam complaints hurt the domain that sends your quotes.
- Segment twice: by what the account was worth and by why it stopped buying.
- Four emails and one call beat a discount. A held price, a shorter lead time or a sample is something a buyer can act on.
- Measure quotes and reorders. A reply is a signal. A purchase order is the result.
Video: a three-email series to win back inactive subscribers
Kate Emiley's 7-minute video is worth watching because she walks through each email of her own re-engagement series, subject lines included, instead of describing the idea in general terms.
Three things worth taking from it:
- The campaign has three acceptable outcomes, not one. People read again, unsubscribe themselves, or stay silent and get removed, and she lists all three as goals, because silent addresses drag down delivery for the people who do read.
- The gift is exclusive, but never a one-on-one call. Her second email offers a discount or a freebie that is not on the site, and she rules out one-on-one offers because hundreds of subscribers could claim them in a day.
- Timing and automation do the cleanup. She waits about three days between emails and seven more after the last one before deleting anyone, and an automation clears the inactive tag from anyone who opens or clicks.
Where we differ: the video is about newsletter subscribers, measured in opens. A B2B list is small enough that the one-on-one offer she rules out, a call from the account owner, is the step worth making for your top accounts, and the result you count is a reorder.
What a win back campaign looks like for a B2B supplier
In a store, a win back campaign goes to people who stopped clicking. In B2B it goes to accounts: a company that bought from you, with a buyer, an account owner on your side and an order history you can read.
| Decision | Typical store win-back | B2B win back campaign |
|---|---|---|
| Who counts as inactive | No opens or clicks in 3 to 6 months | No order for more than twice the account's usual reorder gap |
| Where the list comes from | Engagement data in the email tool | ERP or invoicing system, by account |
| Who sends it | The brand | The account manager or sales engineer, by name |
| The reason to come back | Discount code, free shipping | Held price, lead time, sample, visit, spec update |
| Channels | Email, sometimes SMS | Email plus a phone call |
| What you measure | Clicks and revenue | Replies, quotes requested, reorders |
The order history is the asset. You already know what each account bought, how often, and when it stopped. No competitor can copy that.
Step 1: find dormant accounts in your order history
Export three years of invoices by account with five columns: account, date of last order, number of orders, revenue and main product line. Add the account owner if your system tracks one.
Then work out each account's normal rhythm. A customer that orders monthly and has been silent for four months is dormant. One that buys a machine every three years is not.
A simple rule works for most catalogs: an account is dormant when the time since its last order is more than twice its median gap between orders. Accounts with a single order go in their own group, because they never had a rhythm to break.
Sort the result by past revenue, so the dormant accounts that used to carry the most volume come first. That is where you start.
Clean the contacts before anyone writes a word
Dormant accounts carry old contacts. The US Bureau of Labor Statistics found that the median worker had been with their current employer for 4.1 years in January 2026, and 4.9 years in manufacturing (BLS Employee Tenure Summary, 2026). On an account that went quiet two or three years ago, the buyer you remember may well be gone.
Check every contact at your top accounts by hand: still at the company, same role? A profile search answers that in a minute.
When the buyer has moved on, call the main number and ask who buys that product line now. You get the new name and a reason to talk.
Then protect your domain. The address that sends these emails is usually the one that sends quotes and invoices. Google asks every sender to keep the spam rate reported in Postmaster Tools below 0.3% (Google email sender guidelines), and one blast to three years of stale contacts can be enough to break it.
Verify the addresses, remove hard bounces, and send in small daily batches from the account owner's mailbox. Slower, and much safer.
Step 2: segment by value and by reason for leaving
Two questions decide what each account gets. How much was it worth? Why did it stop?
For value, rank accounts by revenue over the last three years and split them into three tiers. A accounts are the top tier by revenue. B is the middle. C is the long tail of small and one-off buyers.
For the reason, ask the account owner. When they do not know, the order history hints: a steady customer that stopped at once points to a problem or a competitor; one that faded slowly points to a project ending or a buyer leaving.
| Reason for leaving | What usually happened | What the first message does |
|---|---|---|
| The buyer left | New person, no relationship with you | Introduces you and what their company buys |
| Price | A competitor quoted lower | Confirms current pricing on their last part numbers |
| Quality or delivery problem | A late or rejected order | Acknowledges it and says what changed |
| Project or product ended | No current need | Asks what is coming next |
| Switched supplier | Volume moved elsewhere | Offers to be the second source |
| Unknown | Nobody remembers | Asks one direct question |
A accounts get a call from the account owner with the first email. C accounts get email only, because writing to each one by hand costs more than they will order.
The sequence: four emails and one call in three weeks
Every email comes from a named person, in plain text, and asks for one thing. Here is the order, with the time each step takes to prepare:
- Email 1, day 1: the check-in (20 minutes). From the account owner, three sentences: your last order was in March 2024, has something changed, can I help with the next one. No offer yet.
- Email 2, day 5: what changed at your company (30 minutes). One thing that matters to what they bought: a new machine, shorter lead times, a new certification or a revised spec sheet. Link the spec sheet's own page rather than attaching a PDF, as our manufacturing website design guide explains.
- Email 3, day 10: a reason to order now (30 minutes). A quote for their last part number at current pricing, a price held until a date, a sample, or a booth meeting at your next trade show.
- The call, days 12 to 14, A and B accounts only (10 minutes). The account owner reads the first email out loud: no order since March, is there a reason, is anything coming up we can quote.
- Email 4, day 21: close the loop (15 minutes). Ask them to pick one: still buying elsewhere, no need right now, send me a quote, or take me off the list. Every answer is useful.
Set it up as a sequence, not a broadcast. A broadcast is one email sent to a whole list on the same day. A sequence sends each account its next step on its own schedule, and it needs a stop rule: any reply, quote request or order takes the account out at once, so nobody gets the "close the loop" email the day after placing an order.
Accounts that stay silent after Email 4 leave the sequence too. A newsletter would delete them; you keep the account in the CRM, stop marketing emails to that contact and set a reminder to look at the account again in six months.
The first email sets the tone, so keep it short and specific:
Subject: Your last order with us
Hi Dana, I noticed your last order for the 316 stainless fittings was in March 2024. Has something changed on your side? If you have a project coming up, I can quote it this week.
Mark, Account Manager
Write each template once and let every account owner rewrite the first line. The free AI email generator gives you a first draft to cut down.
When someone replies and then goes quiet again, switch to normal sales follow-up: each message adds something new, such as a drawing, a lead time or a price, instead of asking whether they are still interested.
In the US, these are commercial emails under the CAN-SPAM Act, and the FTC states that "the law makes no exception for business-to-business email" (FTC CAN-SPAM compliance guide). Each message needs an accurate subject line, your physical postal address and a working way to opt out. Opt-outs must be honored within 10 business days, and the FTC guide puts the penalty at up to $53,088 for each email that breaks the rules.
How to measure a B2B win back campaign
Measure at the account level, over 90 days from the first email. Five numbers are enough:
| Metric | How to count it | Why it matters |
|---|---|---|
| Replies | Any human reply, including "not now" | The contacts were right |
| Quotes requested | RFQs from campaign accounts | First commercial signal |
| Reorders | Purchase orders from campaign accounts | The result |
| Revenue from reactivated accounts | Invoiced within 90 days | What it was worth |
| Opt-outs and bounces | Counted per batch | Whether the list hurts your domain |
Keep a control group: a handful of dormant accounts, picked at random, that you leave out. Some accounts come back on their own, and the control group stops you crediting the campaign with those orders.
Then log the answers from Email 4 in the CRM. A pattern of "switched supplier" on one product line is not a marketing problem. It is a pricing or quality conversation for leadership.
When several accounts left for the same rival, watch what that rival offers. Our competitor tracking guide sets up a monthly routine.
Common mistakes with a win back campaign
- Sending from a no-reply address. B2B buyers reply to people. Fix: send from the account owner and route replies to them.
- Leading with a discount. It teaches good accounts to wait for one. Fix: lead with the reason they stopped.
- Emailing the whole list on one day. Bounces and complaints arrive together and land on your main domain. Fix: verify addresses and send in small daily batches.
- Writing only to the old buyer. If they left, the email goes nowhere. Fix: check each contact first and call the main number when the person is gone.
- Counting opens. Mail apps with privacy features register opens that never happened. Fix: count replies, quotes and orders.
Frequently asked questions
What is a win back campaign?
A win back campaign is a short sequence of messages sent to customers who used to buy and stopped, with the aim of getting them to buy again. In B2B it targets accounts rather than subscribers: companies with an order history, a buyer and an account owner. It usually means three or four emails, plus a phone call for the accounts that were worth the most.
When should you send a win back campaign?
Send it when an account has been silent for longer than its normal buying rhythm. A practical trigger is no order for more than twice the account's usual gap between orders. For a customer that orders monthly that is about two months; for one that buys equipment every few years it is much longer. Newsletter guides use three to six months without clicks, which suits subscribers better than B2B orders.
How many emails should a win back campaign have?
Three or four emails is the usual answer, and it holds for B2B. With fewer, many buyers never see it; with more, you push on people who have already shown little interest. In a B2B campaign, add one phone call from the account owner between the third and the fourth email for your most valuable accounts. The call often gets the answer the emails did not.
Do you always have to offer a discount?
No. Discounts suit consumer stores, and in B2B they rarely address why an account stopped. A buyer who left over a late delivery wants to know what changed. One who moved to a cheaper supplier wants a current quote. Better reasons to reorder are a held price on the last part number, a shorter lead time, a sample or a visit. Leave price moves on large accounts to sales.
What is the difference between win back and re-engagement?
The terms are often used as synonyms. Win back usually means customers who stopped buying; re-engagement means subscribers who stopped opening or clicking. For a supplier the difference matters: a re-engagement email cleans your list, a win back campaign recovers revenue. You can run both, but measure the win back campaign in reorders and the re-engagement email in list health.
What to do next
In short: a B2B win back campaign starts in your order history, cleans the contacts, segments by value and by reason for leaving, and runs four emails plus a call from a real person. Measure it in quotes and reorders over 90 days.
This week, export three years of invoices and flag every account past twice its usual reorder gap. That list shows how much revenue is sitting still.
If you would rather do it with help, customer reactivation is one of our marketing services for manufacturers. It starts with a free 60-second video audit of how a buyer sees your company on Google and ChatGPT next to three competitors, followed by a quote with a closed scope.
