Before a proposal
How should a business compare bulk SMS and OTP proposals?
Start with the message purpose and the event that triggers it. An OTP journey needs expiry and retry controls; a campaign needs audience rules and a response path. Compare those workloads separately before agreeing volume and routing.
What affects the quotation
Message category, destination and submitted volume
Message length, encoding and resulting segments
API integration, sender setup and support scope
What to bring to discovery
Examples of each message and the system that triggers it
Expected daily volume and peak-minute traffic
Existing sender, template and consent records
A practical pre-launch check
Test an expired OTP, a repeated request and a late delivery. Confirm that a delayed message cannot complete an expired authentication attempt.
Common questions
Useful answers before a proposal.
What is Bulk SMS and OTP?+
Bulk SMS and OTP help organisations deliver approved promotional, service and verification messages at scale through registered sender identities and auditable delivery workflows.
How does EASY SERVE scope Bulk SMS and OTP?+
We review the business objective, intended audience, data and consent context, expected scale, integration points, operational ownership and required measurement before confirming a solution.
Can Bulk SMS and OTP integrate with existing systems?+
Integration depends on the interfaces available in your stack. Suitable APIs, webhooks, CRM fields and security requirements are assessed during discovery.
Should OTP and promotional SMS use one workflow?+
Keep their purpose, templates, access and success measures separate. Authentication should track completed verification and latency; promotions should track permitted audience contact and useful responses.
Why can one text create more than one billable message?+
A message may be split into segments depending on its length and encoding. Have the proposed platform preview the exact text, including regional-language characters, before estimating cost.
Does a delivery receipt prove that a person read an SMS?+
No. Treat delivery status as a transport event. Measure the intended action separately, such as a completed verification, booking or enquiry.
What should we send for a bulk SMS quotation?+
Provide message samples, destinations, route purpose, daily and peak volume, sender readiness and integration needs. Include the expected split between one-off campaigns and automated messages.
How do we avoid sending the same notification twice?+
Agree a unique business-event reference and retry policy. Test duplicate API requests and delayed callbacks so a retried job does not create a second customer notification.
