How Manufacturers Can Automate RFQ Email Responses with AI

There is an RFQ sitting in your sales inbox right now. It came in as an email with a PDF drawing attached, asking for a price on 500 units with a delivery date four weeks out. Nobody has quoted it yet, because your estimator is finishing yesterday's batch and the owner is on the floor.

Meanwhile the buyer who sent it emailed two other shops the same morning. In manufacturing, when price and capability are close, the order often goes to whoever quoted first, not whoever was cheapest.

Disclosure: we make InboxPilot, an AI email assistant that drafts replies to RFQs and customer emails inside Gmail and Outlook. This post explains the workflow and says plainly where a tool like ours does not belong: no AI should be sending a firm price, tolerance, or lead-time commitment without an estimator checking it.

TL;DR

• Manufacturers rarely lose an RFQ because they can't do the work. They lose it in the days between the email arriving and a person quoting it.
• The estimating inbox is filled by five repetitive email types: RFQs, availability and lead-time questions, spec clarifications, quote follow-ups, and reorders.
• Most RFQs do not arrive through a portal. They arrive as email with a spec sheet attached, which is why automation has to start in Gmail and Outlook.
• AI can read the RFQ, draft a quote from your own pricing and specs, and route the inbox, with an estimator approving every number.

Why manufacturers lose RFQs in the inbox

The bottleneck in most shops is not capability or even price. It is the queue in front of the estimator. An RFQ lands, and before anyone can quote it, someone has to open the email, read the drawing or spec sheet, pull out the part number, quantity, material, tolerances, and required date, check availability and lead time, and only then start pricing. That reading-and-extracting step is pure overhead, and it happens for every request, winnable or not.

While that queue moves, the clock runs. The buyer who sent the RFQ is rarely sending it to one shop. When two suppliers can both do the job at a similar price, the faster quote wins a disproportionate share of the time, and the shop that took three days to respond never finds out how close it was.

This is not a hunch about buyer behavior. In a Thomas survey of more than 400 industrial buyers, respondents said they expect supplier responses within 24 hours and quietly drop the slow ones. One put it plainly: "There's nothing worse than no response or hearing back weeks later. If I have to follow up twice, I eliminate you from consideration." (Thomas, 2021).

The frustrating part is that the slow step is the least skilled one. Your estimator's judgment on pricing and feasibility is valuable and hard to replace. The reading, sorting, and re-typing in front of it is not, and it is exactly what eats the hours.

The five emails in a manufacturer's inbox

Ask a shop's sales desk what fills the inbox and you get some version of the same five piles. Every one is repetitive and answerable from information you already have on file.

None of this needs an estimator's judgment to acknowledge and start. It needs fast reading, accurate extraction, and a grounded first draft, which is what software should absorb so your estimator spends time pricing, not sorting.

Most RFQs arrive by email, not through a portal

There is a persistent myth that RFQs live in procurement portals. Some do, at the largest GCs and OEMs and on public work. For most small and mid-size manufacturers and suppliers, the reality is an email inbox with spec sheets and drawings attached. Buyers reach for email because it is universal and low-friction: attach the drawing, hit send, get a number back.

That is why the wave of RFQ and CPQ software mostly misses this buyer. Those platforms are built around a portal and a structured configuration flow, and many target the enterprise or the buyer side of the transaction. They ask your customers to adopt a system, which most will not. The requests keep coming to the inbox, and the inbox stays manual.

That is the gap InboxPilot fills. It is not a CPQ platform and it does not ask your buyers to change anything. It sits in the estimating inbox in Gmail or Outlook and turns it into the front end of your quoting process: reading each RFQ, extracting the details, drafting a quote from your own data, and handing your estimator a number to check instead of a PDF to decode.

What AI can take off your plate

An AI email assistant grounded in your own pricing and capability docs can absorb the repetitive layer of the estimating inbox:

• Read and extract on arrival. Every RFQ is read, including the attached spec sheet or drawing where possible, and the part, quantity, material, tolerances, and required date are pulled into a structured summary your estimator can scan in seconds.
• Draft a quote from your own data. Point it at your price lists, rate cards, capability statement, standard lead times, and past quotes, and it drafts a grounded reply with a ballpark or a firm number where your rules allow, in your company's tone.
• Instant acknowledgement. Even when a quote needs an estimator, the buyer gets an immediate, on-brand reply confirming receipt and next steps, which is what keeps them from awarding elsewhere while they wait.
• Triage and routing. Winnable RFQs, capability mismatches, and sensitive threads get sorted and routed, so nobody's request sits unseen and nothing risky gets auto-answered.
• It runs where your team works. No new platform, no migration, no portal for buyers. Inside the shared sales or estimating inbox in Gmail or Outlook.

The workflow: from new RFQ to approved quote

1. An RFQ lands in the estimating inbox with a drawing attached.
2. InboxPilot reads the email and the drawing, extracts part, quantity, material, tolerance, and required date, and checks your standard lead time.
3. It drafts a reply with your ballpark pricing for that part type, your lead time, and standard terms, and attaches a structured summary of the request for the estimator.
4. It labels the thread "RFQ, needs approval" and surfaces it near the top of the inbox.
5. Your estimator checks the number, adjusts for anything the drawing implies, and sends, the same day, not three days later.

Keep an estimator on the numbers

The honest guardrail: pricing, tolerances, and lead-time commitments stay draft-and-approve. A firm quote carries margin and contract risk, so AI drafts and an estimator sends. Route claims, change orders, disputes, and anything with a complaint in it straight to a person and skip automation entirely. Used this way, the AI does the reading and the first pass, where the hours go, and leaves the judgment to the person qualified to make it.

Frequently asked questions

What is RFQ email automation for manufacturers?

Software that reads an incoming request for quote, extracts the part, quantity, specs, and date, and drafts a reply using your own pricing, capabilities, and lead times. Safe setups keep a person in the loop: the AI drafts, an estimator approves the numbers before sending.

How is this different from CPQ or procurement software?

CPQ and procurement tools are portal-based and often enterprise or buyer-side. Most small and mid-size manufacturers receive RFQs as emails with a spec sheet attached. This works inside the Gmail or Outlook inbox where those requests actually land.

Can AI send quotes without an estimator reviewing them?

It can, but it should not. Pricing and lead-time commitments carry real risk, so the default is draft-and-approve.

How fast should a manufacturer respond to an RFQ?

Faster than most do. When price and capability are close, buyers frequently award to whoever quotes first. Same-day is a reasonable internal bar.

What does it cost?

Free to start (25 AI drafts), paid plans from $29 per month, Standard $149 per month for 1,500 drafts, unlimited inboxes, and knowledge base grounding. Annual billing is about 20% less, priced per workspace.
