Hulaki.Email

Hulaki provider for email, through FreeTierMail.

Status: in development. The API can change until 1.0.

The channel works in one of two modes, set by UseFreeTierMail.

One SMTP server (the default). Set Host, Port, Username and Password:

{
  "Hulaki": {
    "Channels": {
      "email": {
        "Host": "smtp.example.org",
        "Username": "alerts@example.org",
        "Password": "from user secrets",
        "From": "Route alerts <alerts@example.org>"
      }
    }
  }
}

Through FreeTierMail. Set UseFreeTierMail to true and configure the accounts once, in the FreeTierMail section. The mailer picks an account by the quota each has left and fails over when one is throttled, used up or down. Switch accounts per environment with Enabled, for example a local Mailpit inbox in development and a paid Resend plan in production:

builder.Services.AddFreeTierMail(builder.Configuration.GetSection("FreeTierMail"))
    .AddResend()
    .AddSmtp("inbox");
builder.Services.AddHulaki()
    .AddEmail("email", builder.Configuration.GetSection("Hulaki:Channels:email"));

{
  "FreeTierMail": {
    "Providers": {
      "resend": { "PreferForCritical": true },
      "inbox": { "Enabled": false }
    }
  },
  "Hulaki": {
    "Channels": {
      "email": { "UseFreeTierMail": true, "From": "Route alerts <alerts@example.org>" }
    }
  }
}
Fact Value
Recipient an email address
SMTP transport port 587 with STARTTLS required; 465 with TLS from the start; on a loopback host no login is needed and STARTTLS is used when offered
Body a plain text part and an HTML part; markup is rendered into the HTML part
Subject the title, or the first line of the text cut to 78 characters
Priority High and Urgent are critical mail: providers marked PreferForCritical first, and the quota reserve
Outcome Accepted with the provider's message id: the provider queued it, delivery happens later

A refused recipient is RecipientNotFound and an address on the suppression list is RecipientBlocked; neither is retried. Throttles, used-up quotas and outages are retried after a delay, once the mailer has tried every account. When an answer was lost the outcome is Unknown and nothing is resent.

Password and every provider key are secrets: keep them in user secrets or the environment.
