400K

SMS messages sent in under 10 minutes for a healthcare marketing platform. Multi-provider infrastructure built with Golang, AWS SQS, and DynamoDB.

400K
SMS in under 10 minutes

From 90K in 5 minutes to 400K in under 10 minutes. Multi-provider load balancing handled the scale.

$4MM+
ARR generated

Healthcare marketing platform serving major US enterprise clients. Infrastructure costs ~$800/month.

10M+
Messages delivered

COVID-19 healthcare platform. Over 10 million messages sent. 150K+ patients reached. Conversion jumped from 2.2% to 3.7%.

/ The challenge

Healthcare at massive scale

Marketing platform serving major US healthcare companies. Started at 90K SMS in 5 minutes. Scaled to 400K in under 10 minutes. Multi-provider load balancing. Phone number rotation. Carrier compliance built-in.

Simple tech, massive results

Golang for performance. SQS for queuing. DynamoDB for state. Infrastructure costs ~$800/month. Platform generated $4MM+ ARR. That's the power of choosing the right tools.

/ How we built it

Ingestion

REST APIs feeding directly into AWS SQS queues. Messages land in queue first, process second. Zero data loss.

AWS SQS
Processing

Golang workers consuming from SQS. AWS DynamoDB for deduplication and state tracking. Blazing fast, infinitely scalable.

Golang + AWS DynamoDB
Delivery

Multi-provider SMS delivery with intelligent load balancing. Phone number rotation to stay under carrier limits.

Multi-provider SMS
~$9,600/yr infrastructure → $4MM+/yr revenue. That's 400x+ ROI.

What could the right architecture do for you?

Most teams overcomplicate messaging infrastructure. We chose three managed services and built a platform that handles 400K messages in under 10 minutes — for less than most teams spend on coffee.
