OTPs, Alerts and Email That Actually Land

SMS OTP integration is the most common request -- almost always for signup/login verification or checkout confirmation, using a provider like MSG91, Twilio or a local SMS gateway depending on delivery reliability and cost per SMS in India. Twilio itself gets requested specifically when a business also needs voice calls or international SMS, not just Indian numbers.

SendGrid (or a similar transactional email provider) comes up once a business notices their order-confirmation or password-reset emails are landing in spam when sent through a regular hosting mail server -- a dedicated transactional email API fixes that deliverability problem directly. Firebase Cloud Messaging (FCM) is specifically for push notifications on a mobile app or PWA.

Frequently Asked Questions

It's almost always because they're being sent through shared hosting mail rather than a dedicated transactional email API -- switching to SendGrid or similar with proper authentication (SPF/DKIM) usually fixes it.

The provider account (MSG91, Twilio, SendGrid, etc.) is created under your business details since billing and sender-ID approval are tied to you; the integration and testing are handled end to end.

Most projects range INR 5,000-40,000 depending on how many channels (SMS, email, push) are involved.
