How zignature Delivers E-Signature Requests with 99.9% Reliability
For zignature, a missed signature request email costs a deal. They moved to Sendbound for its delivery guarantees, webhook receipts, and retry logic. Here's what that looks like in practice.
zignature is an e-signature platform built for legal, real estate, and financial services teams. When a document is sent for signature, the signer receives an email with a secure link. If that email doesn't arrive, the deal doesn't close. At zignature's scale — hundreds of thousands of signature requests a month — even a 0.1% delivery failure rate means thousands of deals at risk.
Why delivery reliability is non-negotiable
Signature request emails are different from typical transactional emails in one critical way: the recipient has no idea they're coming. Unlike a booking confirmation (where the recipient just made a booking) or a password reset (where the recipient just clicked "forgot password"), a signature request arrives unsolicited. The recipient is often a lawyer, a buyer, or an executive who is suspicious of unexpected email links. This makes both deliverability and trust signals extremely important.
BIMI and brand trust
zignature uses Sendbound's BIMI setup to display the zignature logo next to every email in Gmail and Apple Mail. When a recipient sees a verified brand logo next to an email asking them to click a link, click-through rates improve dramatically. zignature saw a 31% increase in same-session signature completion (signatures completed within 10 minutes of email receipt) after enabling BIMI.
"BIMI was something we'd heard about but never implemented because it seemed complex. Sendbound's setup guide had us live in 45 minutes. The click-through improvement paid for our Sendbound plan in the first week."
Retry and receipt architecture
Sendbound automatically retries soft-bounced signature request emails up to three times over 15 minutes before reporting a hard failure. zignature listens to Sendbound's delivery webhooks — delivery confirmed, soft bounce, hard bounce — and surfaces the status in real time in the sender's dashboard. If a signature request is undeliverable, the sender sees it immediately and can follow up by phone instead of wondering why the deal went quiet.
