MailSendResult

The outcome of a send. Returned rather than thrown, so a caller can decide whether a failed notification should fail the operation around it. Only the package constructs one, so a result always describes an outcome that actually happened.

Fields

IsSuccess: bool
Whether the send succeeded. A false value does not always mean Resend declined it, since a send with no recipient fails before the provider is contacted.

MessageId: string?
Resend's identifier for the accepted message. Use it to correlate a send with a webhook or the Resend dashboard.

Error: string?
The failure description when the send did not succeed, carrying either this package's own rejection or the text the provider returned.

Type signature

public sealed record MailSendResult
{
    public bool IsSuccess { get; }
    public string? MessageId { get; }
    public string? Error { get; }
