May 2022
What a crazy month it has been. I have not seen such revenue numbers before – it starts to look like an actual business. I fear that the coming summer months will break the nice growth curve charts until the fall. Let's wait and see.
My new solo venture is EmailEngine, an email syncing app. I have no investors and no one to report to, but I find it a good exercise to generate a recurring overview of the business, so I'm publishing these reports here.
Highlights
- I changed the pricing at the beginning of the month. The previous subscription price was 250€ + VAT per year. The new price is 495€ + VAT.*
- I released a beta version of ElasticSearch integration. This enables local caching of emails for faster API responses. It also opens up the possibility of data mining over stored emails.
- To drive more web traffic to EmailEngine's homepage, I started featuring it on Ethereal.email, a popular test-email account service. It's another web property that I own and run.
Numbers
April 2022 | May 2022 | MoM | |
---|---|---|---|
Website visits | 2,300 | 4,400 | +91% |
New paying customers | 8 | 7 | -12% |
Total paying customers | 24 | 31 | +29% |
Churned customers | 0 | 0 | - |
MRR ** | $582 | $862 | +48% |
Net cash flow | $1,953 | $3,677 | +88% |

Plans for June
- To improve EmailEngine's API coverage. Currently, EmailEngine can not run write operations over a range of messages, only against a single email. This makes operations like "mark all messages as read" unnecessarily complex.
- Try to get featured on a web property I do not own. So far, the main drivers of traffic have been Nodemailer.com and Ethereal.email, both owned and managed by myself.

* For all the stats, I use dollar nomination, but I sell EmailEngine for euros.
** MRR and cash flow numbers do not match as I sell yearly subscriptions, so customers always pay upfront.
