What an engineer registers for
A manufacturer’s ebook for lead generation earns an engineer’s email when it’s a working file. It’s something they’d otherwise build themselves, and it stays open next to a drawing.
This post starts where 2 others stop. Whether the piece belongs behind a form is settled in which content to gate. Whether your brief describes an ebook at all is the job of white paper vs ebook. Here both answers are yes.
A marketer will skim a guide. An engineer registers when the file saves an afternoon. In where the chain breaks, we kept the early ask small: a criteria list, a spreadsheet or a 2-line answer. A lead gen ebook for engineers is that ask, built out.
Three parts the file needs
The file needs a capability table, an acceptance checklist and a list of what to send with a drawing. An engineer can use each one on a current part this week.
The capability table. What your plant holds, by process, material and size range, and what you measured it with. The figures come from your engineers. As we said in what we write for manufacturers, we don’t make claims about tolerance we can’t source.
The acceptance checklist. What gets inspected on an incoming lot, against which sampling plan, and which papers travel with it. Name the plan by standard and edition. Leave the AQL blank for the engineer’s own drawing.
The RFQ list. What to send with a drawing so your quote comes back without a round of questions. File format, material, annual volume, critical dimensions, finish.
The values stay open on your page, where a buyer can paste them into a thread. The form hands over the assembled file: the table, the checklist with blanks and the RFQ list in one place.
One caution on the label. In the white paper vs ebook post, a figure that someone will challenge points to a white paper and needs a source. If the file reads like a reference, call it a reference file.
Writing that file sits close to our white papers. Your engineers supply the figures, we write around them, and the source list ships with the text. The nurture sequence after a download is a separate job, quoted on its own.
One enclosure moulder’s file
Everything in this section is fiction, from the moulder to the last decimal. The moulder makes PC/ABS enclosures for control electronics, wants engineers’ names, and puts this table on its open page.
| Feature | Size range | Held | Checked with |
|---|---|---|---|
| Linear dimension | up to 60 mm | ±0.07 mm | CMM |
| Linear dimension | 60 to 180 mm | ±0.14 mm | CMM |
| Flatness, lid face | up to 160 mm | 0.22 mm | Surface plate |
| Wall thickness | 1.6 to 3.2 mm | ±0.09 mm | Ultrasonic gauge |
Behind the form sits the working file. Its checklist page starts like this:
Lot check: enclosure, PC/ABS
Plan: ISO 2859-1:2026
AQL (from drawing): ____
Lot size: ____
1. Wall, 4 marked points
2. Boss height, all 6 bosses
3. Lid face flatness
4. Colour against master plaque
With the lot: CoC, resin lot no.In a real file, every figure in that table comes from your quality engineer. Our part is the order, the units and the edition in the header.
Name the standard and its edition
An engineer reads the standard in your header before the numbers under it. A withdrawn edition there costs you the rest of the page.
ISO 2859-1:2026 replaced the 1999 edition of the sampling standard in January 2026. For general geometrical tolerances, ISO 22081:2021 is listed as the replacement for ISO 2768-2. ASME Y14.5-2018 is still the edition in effect for dimensioning and tolerancing.
We’d put the standard and the year at the top of the page, and under them the figures your plant holds against that edition.
Build the form for the engineer
Ask only what an engineer can answer and your sales team will use in the first reply.
LinkedIn Lead Gen Forms allow up to 12 fields, with first name, last name and email selected by default. Up to 3 of the 12 can be custom questions, and “Custom questions are required fields a member needs to answer to submit the form”.
Spend all 3 on the part: material, process, annual volume. An engineer knows those answers. Budget and timeline belong to someone else.
Google’s lead form help names the trade-off: more steps bring fewer leads, but “those leads generally have a greater interest in your business, product or service”.
Ask for a phone number only if someone will call. Article 5(1)(c) of the GDPR requires personal data to be “adequate, relevant and limited to what is necessary”.
The newsletter gets its own box, unticked and optional. LinkedIn lets you mark a checkbox as required, and the GDPR leans the other way. Article 7(4) asks whether a service depends on consent it doesn’t need. Recital 43 presumes such consent isn’t freely given.
The ICO’s consent guidance says “People should not be forced to agree to all or nothing”. If one form serves several markets, build it to the strictest of them, and have your counsel sign off the wording.
Send the file, then mind the emails
The download has to arrive by itself, and every email after it carries an opt-out. Set up both before the campaign goes live.
LinkedIn’s form specifications put it plainly: “LinkedIn doesn’t automatically send any assets to members”. Put an ungated link to the file in the confirmation message, which takes up to 300 characters.
Google Ads stores lead form submissions for 60 days, and its CSV export covers only the last 30. Connect the form to your CRM on day 1, or the first month’s names are gone by the third.
In the US, every commercial email carries an opt-out notice and “a valid physical postal address of the sender”. After an opt-out request, the mail stops within 10 business days. Under GDPR Article 21, the right to object to direct marketing must be stated clearly and separately, by the first message at the latest.
We’d hold the sales call until the engineer replies to something. A call about price on the morning of the download answers a question nobody asked.
When an ebook is the wrong format
Our rule: skip the ebook when the engineer needs one thing you can hand over directly. A form in front of it reads as a wall.
- A CAD or STEP file, a datasheet, a price. Send the file or the quote.
- One table. Publish it as a page with no form. If it sits inside a longer paper, give the paper its own page first, as in how to repurpose a white paper.
- Data that moves faster than you’d reissue a PDF. Lead times, stock and prices belong on a dated page.
- A position with sources behind it. That’s a white paper, and white paper vs ebook covers the difference.

Send the topic, and the engineers you want to hear from, through the quote form. Within 1 working day we’ll reply with the format we’d choose and a fixed price with a delivery date. The format will be one of three: an ebook, a white paper or a page with no form.
