Werde es wohl so lösen, dass ich dauerhaft Strom habe, da ich später gerne weitere Briefkästen am Arduino anschließen möchte.
Bin bei meiner Recherche immer wieder auf diesen Code getroffen:

#include <SoftwareSerial.h>
#define ESP_RX 3
#define ESP_TX 4
#define ESP_RST 8
SoftwareSerial softser(ESP_RX, ESP_TX);
// Must declare output stream before Adafruit_ESP8266 constructor; can be
// a SoftwareSerial stream, or Serial/Serial1/etc. for UART.
Adafruit_ESP8266 wifi(&softser, &Serial, ESP_RST);
// Must call begin() on the stream(s) before using Adafruit_ESP8266 object.
#define ESP_SSID "networkName" // Your network name here
#define ESP_PASS "networkPassword" // Your network password here
char EMAIL_FROM[] = "yourEmail@domain.com";
char EMAIL_PASSWORD[] = "yourEmail'sPassword";
char EMAIL_TO[] = "toEmail@domain2.com";
char SUBJECT[] = "My ESP8266";
char EMAIL_CONTENT[] = "Hello,\r\nThis is a message from your ESP8266.";
// We'll need your EMAIL_FROM and its EMAIL_PASSWORD base64 encoded, you can use https://www.base64encode.org/
#define EMAIL_FROM_BASE64 "yourEmailBase64Encoded"
#define EMAIL_PASSWORD_BASE64 "yourEmail'sPasswordBase64Encoded"
#define HOST "mail.domain.com" // Find/Google your email provider's SMTP outgoing server name for unencrypted email
#define PORT 587 // Find/Google your email provider's SMTP outgoing port for unencrypted email
int count = 0; // we'll use this int to keep track of which command we need to send next
bool send_flag = false; // we'll use this flag to know when to send the email commands
void setup() {
char buffer[50];

// by providing a string to ID the tail end of the boot message:
// comment/replace this if you are using something other than v 0.9.2.4!

ist dieser für mein Vorhaben geeignet? Habe leider noch keine Erfahrung mit dem ESP und habe bis jetzt nur eine Verbindung zum Netzwerk mittels AT-Befehlen hergestellt.
