Cold Email for Contract Manufacturers
We run cold email for shops that make other people’s parts: machine shops, molders, fabricators, EMS providers, assembly houses, and only the email. Your estimators do the quoting and the follow-up, which is what they’re good at, and we do the thing that gets the drawing onto their desk in the first place.
We set up sending domains and mailboxes in your name, build the list every day from OEMs that just announced a product, posted a sourcing job, or started moving production, and write each email for the engineer or buyer who’s going to read it. Starts as low as $2,999 a month, month to month. This page is about who reads the email, how the manufacturing inbox behaves, what a sequence says, and what happens when the reply is a STEP file.
Who reads it
Three people, and they read for different things.
The design or manufacturing engineer reads for process. Can you hold the tolerance, run the material, and do it at the volume on the drawing. They skip anything that sounds like marketing and stop reading at the first claim they can’t check.
The sourcing or supply chain manager reads for risk. Lead time, capacity, certs, second-source coverage, and whether you’ll still be around in three years. Then they forward it to the engineer with one line: “worth a look?”
The owner or VP at a smaller OEM reads for both, fast, on a phone, between a customer call and the floor.
An email that works for all three is short, names their product or their job posting, says process and certification in one line, and asks for a quote on one part. It doesn’t attach a capabilities deck. And it never, ever uses the word “solutions.”
How the manufacturing inbox behaves
OEM buyers are on corporate mail with filters set by an IT department that treats attachments as a threat. A first email with a PDF, a brochure, or a picture goes to quarantine. So: plain text, no attachment, no link until they reply.
A lot of OEMs route new suppliers through a portal. The email’s not the place to fight that. When a buyer writes back “register on our supplier portal,” that goes to your estimator with the link, and the email did its job.
Replies often show up as a drawing or a STEP file with three words of text. That’s the best reply in the industry, and it needs someone on your side who can turn it into a quote in 48 hours. We route it to your estimator’s real inbox, not to some outreach account nobody checks.
And if you’re ITAR registered, nothing controlled goes in an email, full stop. The outreach offers a quote and asks what the part needs. The technical conversation happens after the reply, on your terms.
What the sequence says
Three emails over 12 business days, all about one signal. This one’s an OEM that just announced a handheld device, and the FCC filing showed the enclosure and bracket.
Email 1, day 1.
Subject: Enclosure and bracket quote for the Nova unit
Hi Priya,
Saw the Nova announcement and the FCC filing that went with it. If the enclosure and mounting bracket are still being sourced for the production run, we can quote both off your current CAD, first articles in five weeks, DFM pass included.
Aluminum and stainless, CNC and sheet metal, AS9100 and ISO 13485, in North Carolina.
Can I send a quote on the bracket to start?
Dan
Email 2, day 5, as a reply to email 1.
One thing worth flagging on the bracket from the filing images: the two tapped bosses near the edge tend to give molders trouble at volume, and they’re cheap to move. We’d note that in the DFM. Happy to quote with or without the change.
Email 3, day 12, as a reply to the thread.
Priya, should I close this out, or check back when production sourcing opens? Either’s fine.
Dan
Each one’s under 90 words. First line is the product. Second paragraph is the shop, in one line. The follow-up says something an engineer would find useful whether or not she buys, which is what gets it forwarded to sourcing.
The five signals, and how the email opens
The list gets rebuilt every day from these, and the first line comes from whichever one fired.
A product announcement or an FCC, UL, or CE filing. “Saw the Nova announcement and the FCC filing that went with it.” Then a quote offer on the parts you can see in the filing.
A sourcing, supply chain, or procurement job. “Saw the Supply Chain Manager posting go up.” Then a second-source quote on drawings they already have, so the new hire starts with an option in hand.
A plant, a line, or a capex number. “Congratulations on the Greenville expansion.” Then a question about whether the current supplier can follow the volume, with your capacity number in it.
Production moving out of a country. “Saw the note on moving the housings out of Guangdong.” Then lead time and landed cost, because that’s the spreadsheet they’re in this week.
A hardware startup raising money. “Congratulations on the Series A.” Then a DFM review on the current design, before the pilot run gets quoted.
How the sending is set up
Three to six domains that look like yours, registered in your name, two to four mailboxes each. SPF, DKIM, and DMARC on all of them from day one.
Two to three weeks of warmup before anything real goes out. Twenty to forty emails a day per mailbox.
The sender is a named estimator, sales engineer, or owner. Manufacturing buyers write back to someone who can quote. They don’t write back to a junior rep.
Plain text, no attachment, no image, no link until they reply. Unsubscribe by reply, honored the same day.
Replies, drawings, and portal links go to the sender’s real inbox the same day with the signal attached. You see every reply, including the ones that say no.
When you leave, the domains and mailboxes are transferred to you with the logins.
How it runs
Week one we register the domains, set up the mailboxes, agree with you which processes, materials, and volume ranges you quote, and turn on the five signals across your categories.
Weeks one to three the mailboxes warm. First real sends go out in week two.
From week three, replies and drawings land in your estimator’s inbox with the signal attached. Your team quotes.
Every morning we look at yesterday’s replies and RFQs against the target. If we hit it, we send more. If we missed it, it’s one of four things: wrong OEMs, not enough of them, the email was off, or it didn’t land. We find which, fix it, and that’s what goes out today. You can follow it in the log.
What it costs
Starts as low as $2,999 a month, month to month. No setup fee, no minimum term.
That covers domains, mailboxes, warmup, the list, the signals, the copy, sending, replies, and the daily log.
It doesn’t cover calling or LinkedIn. If you want those run by our team on your account, that’s the outbound program, linked below.
Results
Those are software, logistics, and restaurant clients. We'll put a manufacturing number here the first time a manufacturing client lets us use their name.
Book a 15-minute fit call
Tell us your processes, your certs, and who quotes. We'll tell you whether we'd take the account, what email 1 would say for your categories, and, if it shouldn't be us, who to call instead.

Cold Email for other industries
Questions people ask us
Engineers hate cold email. Why would they read ours?
They hate email about your company. They’ll read email about their part. First line names the product or the filing, second line names the process and the cert, and the follow-up says something useful about the design. That’s a note from one engineer to another, and it gets forwarded.
Can we attach our capabilities statement?
Not in the first email. Attachments from a new domain go to quarantine at most OEMs. Once someone replies, your estimator can send whatever they want from their real inbox.
Our sales engineers are on the road. Who answers the replies?
They do. The replies go to their real inbox, and most of them are a quote request or a drawing. You can acknowledge either one from a phone with “got it, quote by Thursday.” If nobody on your side can do that inside 48 hours, tell us on the fit call and we’ll figure out together whether this makes sense.
We’re ITAR registered. What can the email say?
That you’re ITAR registered, what processes you run, and that you can quote. Nothing about the part beyond what’s in the public filing. Everything technical happens after the reply, on your side, under your controls.
Do we need a landing page or a website update?
No. The email has no link in it. A buyer who wants to check you out will find your site on their own. A clean capabilities page and a current certs page help, and you’ve probably already got both.
How many emails go out?
A few hundred a week across a handful of process categories. The list is OEMs where something happened this month, not every procurement title in a SIC code, so the volume is low and the replies are quotes.
