We share files with lenders and realtors constantly. Email or a portal?

The volume of document exchange in a title transaction is high and the counterparties change every file, so the temptation to just email everything is understandable. Here is why it is the wrong default.

Non-public personal information in email is exposure you cannot recover. Social security numbers, account numbers, loan documents and settlement statements sent by ordinary email sit in your sent items, in their inbox, on their phone, and in whatever backups both sides keep, indefinitely. If either mailbox is compromised, and in this industry they are targeted specifically, everything ever sent is available at once. A portal keeps the document in one controlled place with a record of who accessed it.

Email threads are the attack surface for wire fraud. This is the more important reason. When the whole transaction is conducted over email, a compromised mailbox anywhere in the chain, and it is frequently the realtor's or the borrower's rather than yours, lets an attacker read the timeline, learn the names and tone, and insert a message at the right moment. Moving document exchange and any discussion of funds into a portal removes most of that opportunity.

What works in practice for a title office:

• Portal for documents, especially anything with non-public personal information, and for the closing package.
• Email for scheduling and coordination that contains nothing sensitive.
• Wire instructions never by email, in either direction, with no exceptions and a stated policy that says so to every party at the start of every file. Verbal verification on a number you looked up independently, never a number in the email.
• Encrypted email as a fallback for counterparties who will not use the portal, because some will not.

The realistic objection is that lenders and realtors resist anything with friction. Mostly true, and it is less of a problem than it was, because every lender now has their own portal and the expectation has shifted. Say it once at file opening, in writing, and most parties comply.

We set up and support the portal, the encrypted email fallback, and the monitoring that tells us if a mailbox on your side is behaving oddly. What has to come from you is the policy and the consistency, because an exception made once for a difficult realtor is the exception an attacker needs.
