Birthday Manager

Self-hosted birthday reminder application that automatically e-mails people on their birthday.

Features

Page 1 — Dashboard

Three panels at the top: Yesterday's Birthdays, Today's Birthdays (with the Force Send button to resend the e-mail) and Tomorrow's Birthdays
Add / remove birthday entries: First Name, Last Name, Date of Birth, Gender, E-mail address
Yearly calendar overview of all entries (hover a marked day to see the names; browse other years)

Page 2 — Administration

Add / remove application users
Every user can enable/disable MFA (TOTP — Google Authenticator, Authy, etc.) and change their own password
Full e-mail log: who received mail, at what date & time, and whether it succeeded
Setting for the time of day the automatic birthday e-mails are sent (applies immediately, no restart needed)
Two template zones: E-mail Template Male and E-Mail Template Female, with placeholders {first_name}, {last_name}, {age}
Image upload — select multiple files at once (15 MB total per upload); each image shows its ready-to-copy <img src="/uploads/…"> command, and images are embedded inline in the outgoing e-mail

Automatic sending: a scheduler runs every day at SEND_HOUR (default 08:00) and e-mails everyone whose birthday it is, using the template matching their gender. Duplicates are avoided (one automatic mail per person per day); Force Send always resends. February 29 birthdays are celebrated on February 28 in non-leap years.

Every successfully sent e-mail is also copied to the mailbox's Sent folder via IMAP, so it shows up in your normal mail client.

Mail provider

The app comes pre-configured for Purelymail:

	Server	Port	Security
Outgoing (SMTP)	`smtp.purelymail.com`	`465`	SSL/TLS
Incoming (IMAP, Sent-folder copy)	`imap.purelymail.com`	`993`	SSL/TLS

You only need to fill in SMTP_USER, SMTP_PASS and SMTP_FROM with your Purelymail mailbox credentials. If your network only supports STARTTLS for SMTP, set SMTP_PORT=587 and SMTP_SECURITY=starttls instead. Any other provider works too — just override the host/port variables.

Quick start (Docker — recommended)

Edit docker-compose.yml and fill in your Purelymail credentials (SMTP_USER, SMTP_PASS, SMTP_FROM) plus a random SECRET_KEY and your timezone.
Run:

docker compose up -d --build

Open http://localhost:8080 and log in with admin / admin — then change the password on the Administration page immediately.

All data (SQLite database + uploaded images) lives in ./data, so back up that folder.

Quick start (plain Python)

pip install -r requirements.txt

# Purelymail servers are the built-in defaults - only credentials are needed
export SMTP_USER=you@yourdomain.com
export SMTP_PASS=your-purelymail-password
export SMTP_FROM=you@yourdomain.com
export SEND_HOUR=8
export SECRET_KEY=$(python -c "import secrets;print(secrets.token_hex(32))")

python app.py

The app listens on port 8080 (PORT env var to change). Data is stored in ./data (DATA_DIR env var to change).

Environment variables

Variable	Default	Purpose
`SMTP_HOST`	`smtp.purelymail.com`	SMTP server
`SMTP_PORT`	`465`	SMTP port
`SMTP_USER`	–	SMTP username / mailbox
`SMTP_PASS`	–	SMTP password
`SMTP_FROM`	`SMTP_USER`	From address
`SMTP_SECURITY`	`ssl`	`ssl`, `starttls` or `none`
`IMAP_HOST`	`imap.purelymail.com`	IMAP server for the Sent-folder copy
`IMAP_PORT`	`993`	IMAP port (SSL/TLS)
`IMAP_USER`	`SMTP_USER`	IMAP username
`IMAP_PASS`	`SMTP_PASS`	IMAP password
`IMAP_SENT_FOLDER`	`Sent`	Mailbox folder sent mail is stored in
`SEND_HOUR`	`8`	Default hour for the daily send — the time picked on the Administration page overrides this
`SECRET_KEY`	random	Flask session key — set it so logins survive restarts
`PORT`	`8080`	HTTP port
`DATA_DIR`	`./data`	Where the database and uploads are stored

Notes

The e-mail address field on entries is required because it is where the birthday greeting is sent.
Failed sends (e.g. SMTP misconfigured) are also recorded in the e-mail log with the error as tooltip on the "Failed" status. If a mail is delivered but the IMAP copy to the Sent folder fails, the mail is still logged as Sent and the IMAP error appears as a tooltip.
Run behind a reverse proxy (nginx / Caddy / Traefik) with HTTPS if you expose it beyond your LAN.
