Email deliverability for proptech
Where the addresses come from
- Tenant sign-ups, often entered by the agent rather than by the tenant.
- Landlord accounts, business or personal addresses attached to payments and legal notices.
- Trade firm and repair supplier records, small business addresses on a wide spread of domains.
- Property inquiry forms from portal listings, which behave like any consumer capture.
Some of this mail is legally required
Tenancy contact carries legal requirements in many countries: notice periods, deposit information, safety certificates. When delivery of those is handled through a platform, a bounced message becomes a compliance question rather than a support ticket.
The chain makes it harder. A repair request involves a tenant, an agent and a trade firm, and a failure at any point stalls the job while everyone waits for somebody else.
Addresses are also often entered by a third party. An agent types a tenant's address during onboarding, and the tenant never confirms it because the confirmation went to the wrong place.
What the results tend to look like
Mixed and unusually wide. Consumer addresses for tenants, business domains for agents and landlords, and a long tail of small trade firms on every kind of hosting. The trade-firm segment produces more domain-level failures than any other part of the platform.
What to do about it
Validate any address entered by a third party
An agent typing a tenant's address is the least solid capture in the system, and it is also the one that decides whether the tenant can use the platform at all.
Surface failed delivery in the interface
The agent who entered the address is the person who can fix it, and they need to see the failure on the record rather than in a bounce log.
Treat legal notices as a separate stream
Where delivery carries legal weight, it needs monitoring and evidence rather than a place in the general sending queue.
Check trade-firm records on a schedule
Small firms change email providers, wind up and rebrand more often than larger firms, and the domain-level failures show up clearly.
Questions people ask
Why are third-party entered addresses a problem?
Because nobody confirms them. The agent types what they were told, the tenant never receives the invitation, and the error surfaces as an engagement problem rather than a data one.
Does a bounced tenancy notice have legal implications?
It can, depending on the country and the notice. Where delivery carries legal weight, a bounce is a compliance matter and should be handled as one.
Why do trade-firm addresses fail more often?
Small firms change providers, rebrand and close more often than larger firms, and those failures happen at the domain level, which is fast and confident to detect.
