Email Deliverability & Inbox Placement Tools3 min readUpdated September 2026

The Lender Says Your Loan Package Never Arrived

The lender says the package never arrived. You have the sent item, the attachment, and a timestamp, and none of that matters once a credit officer's mail gateway has quietly quarantined your domain without telling anyone on either side. Deal flow in commercial debt advisory depends on a short list of lender inboxes, and that changes what a deliverability fix should actually optimize for.

Here are the questions worth answering before you pick between InboxAlly and Mailreach, ideally before the next closing deadline rather than in the middle of one.

Is the problem one lender or your whole lender list?

Check placement specifically against the mail platforms your active lenders use, not a generic consumer benchmark that tells you nothing about a bank's own gateway. If one credit officer's inbox is the only one affected, that's worth a direct call to their IT desk before you touch your broader sending setup. If several lenders on similar platforms are showing the same pattern, that points to a domain-wide issue worth treating with a real fix rather than isolated troubleshooting one relationship at a time.

Why bank gateways behave differently than ordinary inboxes?

Lender-side mail gateways, especially at larger institutions, often apply stricter filtering than a typical business inbox, sometimes quarantining anything that resembles a bulk sender pattern regardless of content. A brokerage sending both loan packages and a broader market-update newsletter from the same domain can trip that filtering with the newsletter and lose the package along with it, even though the package itself was never the problem.

What should stay separate from marketing mail?

Loan packages, term sheets, and closing coordination are the highest-stakes mail a brokerage sends, and they deserve a sending identity dedicated to that purpose alone, kept apart from market commentary or prospecting content aimed at a broader audience. That separation means a market-update send that a lender's filter treats skeptically can't take down the actual package a deal is waiting on.

When does monitoring make sense versus a rescue?

Mailreach checking placement continuously against your lender list catches a slide before the next package needs to go out, which matters given how few lender relationships most brokerages actually work with on a regular basis. If a package has already been quarantined and a deal is waiting, that's when InboxAlly's active rebuilding earns its cost, since a live deal doesn't have weeks to wait for organic reputation recovery through normal engagement alone.

What to do the moment a lender says they never got it

Confirm placement for that specific send before resending blindly through the same channel that may have already failed once. If the domain is filtered at that lender's gateway, a second attempt through the same identity is likely to fail the same way, and a phone call to arrange a secure portal upload or a direct contact may be faster than waiting on a technical fix mid-deal.

When a lender says a package never arrived, work through these steps:

  1. Confirm placement for that specific send at the lender's mail platform before resending through the same channel that may have already failed.
  2. Call to arrange a secure portal upload or a direct contact, which may be faster than waiting on a technical fix mid-deal.
  3. Check whether other lenders on similar platforms show the same pattern, since that points to a domain-wide issue rather than one credit officer's gateway.
  4. If only one lender is affected, call that institution's IT desk before touching your broader sending setup.
  5. Start an active rebuild with InboxAlly if the domain is filtered at several lenders and a deal is waiting.

Where your numbers should sit against the industry baseline

Mailchimp's benchmark puts the average open rate across all industries at 35.63 percent1. A loan package sent to a credit officer actively underwriting the deal should perform far above that general baseline, since it's mail they're specifically waiting on to move the file forward. A pattern of packages tracking near that all-industry average is worth investigating before the next closing deadline arrives and there's no time left to fix it properly.

Building the check into the closing checklist

Rather than treating a placement check as a special step only reached for after something has already gone wrong, put it on the standard closing checklist next to title work and insurance binders: confirm placement at the assigned lender's platform as soon as the file is assigned, not the week the package is due. That timing gives a brokerage enough runway to switch to a portal or a direct call if a filtering issue turns up, instead of discovering it the same day a credit officer says the package never arrived and the clock is already running.

What this looks like across a small brokerage's whole lender roster

Most commercial mortgage brokerages work a relatively short, repeat list of lenders across their deal flow, which makes a full placement audit manageable in an afternoon rather than the sprawling exercise it would be for a business with thousands of individual contacts scattered across countless providers. Run the check once across every active lender relationship, note which ones show any weakness at all, and revisit that specific subset before every closing wave rather than re-auditing the entire roster from scratch each time. The lenders that show clean placement today are unlikely to need frequent rechecking unless something changes on their end.

Executive Capability Standard

What Good Looks Like

A commercial debt advisory brokerage verifies loan packages and term sheets reach lender inboxes at the specific institutions it works with, checked by lender rather than a general average, with marketing kept off the domain that carries live deals.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Identify the mail platforms your active lenders use and check current placement against each one specifically.
2. Do Manually:Separate loan packages and closing mail from market-update content onto a distinct sending identity.
3. Delegate:Give the deal team a habit of checking placement before resending a package through the same channel that may have failed.
4. Automate:Run Mailreach continuously against your active lender list so a slide shows up before the next package goes out.
5. Buy:Bring in InboxAlly when a package has already been quarantined and a live deal can't wait on organic recovery.

Frequently Asked Questions

How do we find out if a specific lender's gateway is filtering our mail?

A placement check against that lender's specific mail platform will show whether your domain is landing in the primary inbox or being filtered before a human even sees it. This is more reliable than asking the lender directly, since most credit officers have no visibility into their own institution's gateway-level filtering rules.

Should we use a portal instead of email for loan packages going forward?

Many lenders prefer a secure portal for sensitive documents regardless of deliverability, and it removes email filtering as a variable entirely for that specific document type. It's worth using where a lender offers one, while still fixing email deliverability for everything else, term sheet discussions, closing coordination, that doesn't fit a portal workflow.

How fast can we know if a rescue is actually working?

Meaningful improvement typically builds over a couple of weeks as engagement signals rebuild rather than showing up overnight. Track placement at the specific lenders that matter most during that window so you can confirm progress rather than assuming it based on the calendar alone.
