TL;DR: Email-only agreement workflows create delay, missed signatures, and compliance exposure, while SMS and multichannel notifications improve completion rates and speed in customer-facing processes, according to OneSpan and cited market research. The identity lesson is that digital agreement flows now depend on channel reach, consent handling, and controlled delivery as much as on the signature step itself.

By the numbers:
- 84 % des consommateurs ont choisi de recevoir des SMS de la part des entreprises en 2025.
- Les SMS ont un taux d'ouverture de 98 %, dont 90 % sont lus dans les trois minutes.
- 72 % des sociétés financières ont intégré les SMS dans leurs stratégies de communication.
Questions worth separating out
Q: How should organisations use SMS in eSignature workflows without creating compliance risk?
A: Use SMS only where the organisation can prove consent, maintain opt-out handling, and preserve an auditable record of when and why the message was sent.
Q: Why do email-only agreement flows cause more business friction than teams expect?
A: Email-only flows depend on inbox behaviour, spam filtering, and user attention, all of which are outside the organisation’s direct control.
Q: What breaks when consent tracking is missing from multichannel signing journeys?
A: The organisation can no longer show that SMS reminders were lawful, properly targeted, or revocable.
Practitioner guidance
- Map critical agreement journeys by completion risk Identify which contracts, disclosures, and approvals fail most often in email-only flows, then classify them by business impact, signer type, and jurisdiction.
- Separate consent evidence from message delivery Store opt-in, opt-out, and channel preference records alongside the workflow record so compliance teams can prove lawful communication after the fact.
- Define SMS usage rules for regulated workflows Limit SMS to workflow events that benefit from short, time-sensitive prompts, and document when the channel must fall back to email.

Multichannel eSignature notifications: what IAM teams need to know?

Multichannel notifications are a workflow governance problem, not just a customer experience upgrade. The article correctly frames email-only agreement flows as too slow for modern business, but the deeper issue is control reliability across the signature journey. If the organisation cannot reach the signer when the workflow needs action, the business process becomes fragile. Practitioners should treat channel strategy as part of identity-enabled workflow governance, not as a marketing convenience.
A few things that frame the scale:
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools, according to the Ultimate Guide to NHIs.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, which shows how often lifecycle control lags operational use.
A question worth separating out:
Q: Who should own multichannel notification governance in digital agreement programmes?
A: Ownership should be shared across identity, legal, compliance, and operations, because the control spans user identity, communication rights, and workflow outcomes. IAM teams should govern the lifecycle of recipient permissions and the audit trail, while business teams manage the process timing and completion requirements.
