Email Deliverability & Inbox Placement Tools3 min readUpdated September 2026

The Worksheet That Shows Where a Service Quote Went

A worksheet that checks whether each unanswered service quote reached the inbox shows whether lost business is a deliverability problem. Quotes, maintenance reminders, and parts notices go to people who check mail between shifts on locked down corporate systems, and a filtered message looks identical to no response from the sales side. Rule that out before blaming pricing, timing, or a competitor.

Here's a worksheet you can build in an afternoon to find out how much of your lost business is actually a deliverability problem before you assume it's pricing, timing, or a competitor simply doing better work than you did on the last job, none of which you can fix until you rule out the simpler explanation first.

Column one: list your last twenty quotes and their outcomes

Start with a simple table: quote date, customer, plant contact, and outcome, won, lost, or no response. "No response" is the category worth interrogating, since it's the one most likely to be hiding a placement problem rather than a genuine decision not to move forward with the repair or replacement. Most shops have this data sitting in a CRM or a shared spreadsheet already; the work here is pulling it into one place and being honest about how many quotes actually fall into that ambiguous no-response bucket rather than folding them quietly into "lost on price" without checking.

Column two: check placement for each no-response quote

For every quote marked no response, check whether that specific email actually reached the primary inbox at the contact's provider, rather than assuming it did because your platform shows it as sent. Sent and delivered to the inbox are two different things, and the gap between them is exactly what a placement check reveals that your sending platform's own dashboard usually can't tell you on its own, since most sending tools only confirm the message left your server, not where it landed once it got there. A message can show as successfully delivered in your own system while sitting in a spam folder the plant contact never opens.

Column three: group by mail provider, not by customer

Plants running on corporate Microsoft tenants behave differently than a smaller shop on a hosted Gmail plan, and grouping your no-response quotes by provider rather than by customer name often reveals the actual pattern hiding in the data. If every no-response quote to Microsoft-tenant contacts shares a placement problem while Gmail contacts respond normally, that's a specific, fixable issue rather than a general sales problem that would need a completely different kind of fix from your account managers.

Column four: decide between monitoring and a rescue based on what you find

If the worksheet shows scattered placement issues at a couple of providers, ongoing monitoring with Mailreach lets you catch the next one before it costs a quote, checking release by release rather than only after a competitor wins the business you should have had. If it shows a domain that's filtered broadly across most of your quote list, spanning several providers rather than one, that's a deeper reputation problem, and it calls for InboxAlly's active rebuilding rather than more measurement of a problem you've already confirmed is real and already costing you active business.

Column five: separate maintenance reminders from the quote pipeline

Recurring maintenance reminders and parts notices often go to a broader list than active quotes, including plants you haven't done business with in years and may never hear from again. If that reminder list shares a domain with your live quote pipeline, a stale reminder list can be quietly dragging down the mail that's currently trying to win new work from a plant manager who's actively comparing you against a competitor right now. Splitting sending identities protects the higher-stakes mail from the lower-engagement list without requiring you to change how either one is written, and it's a change most service management platforms support without any real disruption.

What the worksheet should show once the fix is working

Across every industry Mailchimp benchmarks, the average open rate comes out to 35.63 percent1. A quote sent to a plant contact who requested it should clear that baseline comfortably, since it's mail they're actively expecting and waiting on before making a decision about the repair. Once your worksheet consistently shows placement confirmed rather than unknown for new quotes, you can trust a "no response" outcome as an actual decision rather than a possible filtering problem in disguise, which changes how your sales team should follow up on it and how honestly you can forecast the pipeline.

Work through the worksheet in this order:

  1. List your last twenty quotes with date, customer, plant contact, and outcome, and be honest about how many fall into the no-response bucket.
  2. Check whether each no-response quote reached the primary inbox at the contact's provider, rather than trusting your sending platform's sent status.
  3. Group the no-response quotes by mail provider instead of by customer name, and look for a pattern such as every Microsoft tenant contact going quiet.
  4. Choose ongoing monitoring for scattered issues or an active rescue for a domain filtered across most providers, based on what the grouping shows.
  5. Move maintenance reminders and parts notices off the domain that carries your live quote pipeline.
Executive Capability Standard

What Good Looks Like

An industrial equipment service company confirms every active quote reaches its plant contact's primary inbox, checked by provider, with maintenance reminders kept on separate infrastructure from the live quote pipeline.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Build the twenty-quote worksheet and find out how many no-response outcomes actually trace back to a placement problem.
2. Do Manually:Separate maintenance and parts-notice mail from the active quote pipeline onto its own sending identity.
3. Delegate:Give sales ownership of checking placement before writing off a quote as lost to price or timing.
4. Automate:Run Mailreach continuously across the mail providers your plant contacts use so a slide shows up before it costs a quote.
5. Buy:Bring in InboxAlly when the worksheet shows placement problems broadly across the quote list rather than at one provider.

Frequently Asked Questions

How do we check whether a specific quote actually landed in the inbox?

A placement monitoring tool like Mailreach tests delivery to seed accounts at major providers and reports back on where mail landed, which is different from your sending platform's own delivery confirmation. Delivered to a mail server and landing in a primary inbox are not the same thing, and the gap between them is where lost quotes tend to hide.

Is it worth calling every plant that doesn't respond to a quote?

For high-value quotes, yes, a quick call is a reasonable backstop while you're diagnosing whether deliverability is the issue. For routine, lower-value quotes, building the worksheet habit and fixing the underlying domain problem is a better use of time than calling every account individually.

Should parts notices and service quotes share a sending domain?

Separating them limits how much a lower-stakes notice list can affect your highest-value mail. Parts notices tend to go to a broader, less engaged list, while quotes go to specific contacts actively evaluating a purchase, and the two deserve different reputation protection.
