Collection workflows require demand letters with proof of mailing. mailbox.bot sends certified mail via API — your system generates the letter, we print and mail it, and delivery proof logs automatically for compliance.
Most collection systems can generate the demand letter, but the physical mailing step still involves manual printing, post office trips, or a separate vendor portal. mailbox.bot eliminates that gap: your collections agent or billing system POSTs a PDF and we handle certified mail fulfillment. FDCPA-required proof of service is captured digitally.
An invoice crosses an aging threshold, a payment plan defaults, or a collections queue flags an account. The system decides — not a human remembering to send mail.
A demand letter PDF generated from the account data: balance, terms, cure period, payment instructions, and required legal disclosures.
One API call with mail_class=certified. mailbox.bot prints the PDF, stuffs the envelope, applies certified postage, and hands it to USPS.
USPS certified mail tracking number, photo proof of the mailed piece, delivery confirmation events, and optional signed return receipt.
Delivery confirmation updates the account record. If no response within the cure period, the system can trigger escalation: second notice, referral, or legal action.
FDCPA and state regulations often require proof that the debtor was notified. Certified mail with tracking provides that proof. Email does not.
Billing system or collections agent flags the account as eligible for a demand letter based on aging, balance, or payment history.
System assembles the PDF with account details, balance, cure period, payment instructions, and required FDCPA disclosures.
POST the PDF to mailbox.bot with mail_class=certified. We print, stuff, stamp, and mail. You get a tracking number immediately.
Delivery events update the account. No response within cure period triggers the next step: second notice, legal referral, or writeoff.
The legal requirement is the same. The operational cost is not.
| Dimension | Traditional mail | Agentic mail |
|---|---|---|
| Letter generation | Staff manually creates or tweaks each letter. | System generates personalized letters from account data automatically. |
| Mailing | Someone prints, stuffs envelopes, and goes to the post office. | One API call per letter. Certified postage applied automatically. |
| Proof of service | Paper receipts filed manually. Easy to lose or misfile. | Digital tracking + photo proof logged to account record automatically. |
| Follow-up | Someone checks manually whether the debtor responded. | System tracks delivery and triggers escalation rules on deadlines. |
| Scale | Sending 200 demand letters takes days of staff time. | Sending 200 demand letters takes minutes of compute time. |
Use the deeper proof pages for vertical value. Keep the homepage clean. Let the agentic thesis do the framing.
