Send a email with Wifi

Hi everyone,

I want to send a email with te following code but than with a variable what stores the mailadres.
Is this possible?

Serial.println(F(“Sending To”));
strcpy_P(tBuf,PSTR(“RCPT To: email@email.com \r\n”));
client.write(tBuf);
if(!eRcv()) return 0;

Something like this:

Serial.println(F(“Sending To”));
strcpy_P(tBuf,PSTR(“RCPT To: <”+variablemailadres+"> \r\n"));
client.write(tBuf);
if(!eRcv()) return 0;
