Modify send mail procedure

douglasfilipe you can create a table to store the mail information and then replace the sp_send_dbmail with an INSERT INTO statement using this modified procedure:

CREATE TABLE dbo.MailLog (
    ID INT IDENTITY(1,1) PRIMARY KEY,
    RecipientEmail NVARCHAR(255),
    Subject NVARCHAR(255),
    Message NVARCHAR(MAX),
    SentDateTime DATETIME DEFAULT GETDATE()
);

-- Modify the procedure
ALTER PROCEDURE [dbo].[SendMailMessage]
(
    @AMEI INT,
    @DeclarationID UNIQUEIDENTIFIER,
    @Action NVARCHAR(50)
)
WITH EXECUTE AS CALLER
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Get the mail message(s)
    DECLARE
        @Role NVARCHAR(50),
        @MailSubject NVARCHAR(255),
        @MailMessage NVARCHAR(MAX),
        @LogMessage NVARCHAR(MAX),
        @OwnerAMEI INT,
        @OwnerFullName NVARCHAR(255),
        @RecipientAMEI INT,
        @RecipientFullName NVARCHAR(255),
        @RecipientEmail NVARCHAR(255),
        @RecipientLanguageCode CHAR(2),
        @AssessmentYear INT

    -- An item in the outbox can have multiple receivers
    DECLARE cur_messages CURSOR FOR
        SELECT mm.[Role], ISNULL(mm.Subject, mm.Subject), ISNULL(mm.Message, mm.Message)
        FROM WF_MailMessages mm
        WHERE mm.Action = @Action
            AND mm.LanguageCode = 'EN'

    OPEN cur_messages
    FETCH NEXT FROM cur_messages INTO @Role, @MailSubject, @MailMessage

    WHILE @@FETCH_STATUS = 0 BEGIN
