Envello in production: our first three months of sending
Before asking anyone to trust Envello with their email, we moved our own products onto it. Aktai, Nakshara, AIM Trader and Stackbastion all send through Envello in production. They share a founder with Envello, so this isn't an independent customer story, and we'd rather say that up front. What it is: three months of real traffic, with numbers straight from the production database.
What's sending
Aktai, a stock-portfolio monitoring product, sends most of the volume: daily pre-market and end-of-day briefings, price and news alerts for watchlisted stocks, trial and verification emails, and occasional product announcements. Nakshara, an astrology app, sends sign-in links, festival reminders and generated reports, some of them in Hindi. AIM Trader sends onboarding emails. Stackbastion sends a small number of account emails.
Each product sends from its own subdomain (for example mail.aktai.app) with SPF, DKIM and DMARC in place, through AWS SES in Frankfurt.
The numbers
Delivery outcomes come from SES events, which Envello has ingested since 28 July 2026. These figures cover live sends from that date to 28 October 2026.
| Measure | Value |
|---|---|
| Live emails sent | 4,729 |
| Delivery confirmed by the receiving server | 4,580 (96.8%) |
| Bounced | 31 (0.66%) |
| Spam complaints | 0 |
| No delivery event recorded yet | 118 (2.5%) |
| Median time from API call to handoff to SES | 0.31 seconds |
| 95th percentile time to handoff | 3.5 seconds |
Volume by month
All live sends, including the days before event ingestion started.
| Month | Live emails |
|---|---|
| July 2026 (from the 21st) | 182 |
| August 2026 | 960 |
| September 2026 | 978 |
| October 2026 (to the 28th) | 2,646 |
What the numbers don't show
The 118 sends with no recorded outcome are the gap we're watching. A missing event can mean a message is still being retried by the receiving server, or that an event didn't reach us. Either way it's the number we want closer to zero, and we'll report it again.
This is also small volume. A bounce rate of 0.66% on 4,729 messages says the setup is sound, not that it will hold at a million. The bounce rate & complaint rate thresholds that mailbox providers enforce are the bar we measure against, and the monthly deliverability report will track them as volume grows.
Why publish this
An email API asks you to trust it with password resets and invoices. A logo wall from companies you can't call doesn't earn that. Real numbers, with the caveats left in, are a better start. When outside customers are sending at volume, their numbers go here too, with their permission.
