Send FastAPI mail through SecureSMTP

Set up in under five minutes

Same flow for every integration: account → credentials → paste into FastAPI → test send.

1. 1

   Create a free SecureSMTP account

   Sign up at securessmtp.com/signup. Free tier covers 100 emails/month — no card required.

2. 2

   Create an API key

   Dashboard → Settings → API keys → Create. Store it in your environment (e.g. SECURESMTP_API_KEY in .env). Never commit it.

3. 3

   Install or import the SDK

   pip install securessmtp-python · or use httpx.AsyncClient to POST directly.

4. 4

   Make your first send

   Copy the snippet below into a server-side endpoint or background job. Replace the to/subject/html with your own values.

5. 5

   Test, then ship

   Trigger your endpoint in dev. Check the dashboard activity feed to confirm the send. Ship to prod — same code, no config swap.

# main.py
import os, httpx
from fastapi import FastAPI, Request

app = FastAPI()

@app.post('/api/contact')
async def contact(req: Request):
    data = await req.json()
    async with httpx.AsyncClient() as client:
        await client.post(
            'https://api.securessmtp.com/v1/mail/send',
            headers={'Authorization': f"Bearer {os.environ['SECURESMTP_API_KEY']}"},
            json={'from': 'site@yourdomain.com',
                  'to': 'you@yourdomain.com',
                  'subject': 'Contact',
                  'html': data['message']},
        )
    return {'ok': True}
