So Actually i did everything as told and my code is the same as yours i did 2FA on the sendgrid and i confirmed my mobile number too.
– I also did a Sender Authentication From where to where it needs to go // is this necessecary?
– I used the SMPT Relay where i made an api key and i used it for the apikey and apikey passowrd // is this correct?
– When i send a mail through arduino the Intnernet is working because i can see that it makes TCP connection to Sendgrid servers.
– Im sending from an Outlook Email to a Gmail Email and i dont know if that is right.

-do you need to pay sendgrid at anypoint because i want to use it for my self and send some email time to time ?

Hee i will put my Code (i want it to keep it very simple) maybe you can see any mistakes 🙂

#include <Ethernet.h>
//#define DEFAULT_EMAIL_NETWORK_TYPE_ARDUINO   NETWORK_W5100
#include <Arduino.h>
#include <SPI.h>
#include <EMailSender.h>
 
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
 
EMailSender emailSend("apikey", "apikey-psw", "<my sendgrid email>", "smtp.sendgrid.net", 587);
 
void setup()
{
    // Open serial communications and wait for port to open:
    Serial.begin(9600);
//    while (!Serial) {}
 
    Serial.println("Starting!");
 
    // start the Ethernet connection:
    if (Ethernet.begin(mac) == 0) {
      Serial.println("Failed to configure Ethernet using DHCP");
      while(1);
    }
    Serial.print("IP address ");
    Serial.println(Ethernet.localIP());
 
 
    EMailSender::EMailMessage message;
    message.subject = "This is a Test";
    message.message = "Its a Test";
 
    EMailSender::Response resp = emailSend.send("the email i want the maessage to go", message);
 
    Serial.println("Sending status: ");
 
    Serial.println(resp.status);
    Serial.println(resp.code);
    Serial.println(resp.desc);
}
 
void loop()
{
    Serial.begin(9600);
    Serial.println("Starting!");
}

Thank you because im trying for a Week to get this working 🙂

Hello,

Could we go on a Call about this. I dont quite understand the part of the confirmation app on the phone.

Bye

Hey I tried your Code but could you tell me more detailed how did you set up the SendGrid because i think i have everything good exept that.

thanks

How could i save some more memory in the UIPEthernet library?

Thank you, Erjon.

-And im using the EMailSender library and Ethernet library but my Bytes are full and i cant execute the Code. Is there any minimised version for w5100.

– im trying the method with sendgrid where i put API, Email, etc. But my Bytes are full and i wanted to ask do you have any idea or maybe another library i could use so that my code would be optimized to work when i add more stuff ?

Thank you,
Erjon

And are there any firewall rules which i have to look closely or that could cause me problems to not be able to send an email?
