I followed installation instructions, used correct libs, and programmed ESP8266 (no Arduino) OK to send an email message using:“My@email”, “Blynk_test01”, “My Blynk project is online.”);
and also noticed the comment in:

However, did not succeed. I did receive the “Auth Token for my project” by email.
What could be wrong?

I suppose you are using Blynk Cloud? Right? Please post your code here.

Yes I do use the cloud + app, I have the app running on an iPhone. When running the code (below) on an ESP8266 I did get positve responses and 1 ms pings, but no email message sent.
Today I got a response:
[53195] Connecting to
[53390] Invalid auth token

and my email + password for the app do not match anymore. I did reset the password, but was not able to log in. I will wait and try again later. My code:

/#define BLYNK_PRINT Serial
/#include ESP8266WiFi.h
/#include BlynkSimpleEsp8266.h …// left out the <> here , messes up the layout in the post

// set up Wifi
const char* ssid = “xxx”; // taken out for this post
const char* password = “xxx”; // taken out for this post

// Create an instance of the server, specify the port to listen on as an argument
WiFiServer server(80);
WiFiClient client;

// You should get Auth Token in the Blynk App. Go to the Project Settings (nut icon).
char auth[] = “xxx”; // taken out in this post

void setup()

// Connect to WiFi network
Serial.print("Connecting to ");
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
Serial.println(“WiFi connected”);

// Start the server
Serial.println(“Server started”);
// Print the IP address
Serial.println( WiFi.localIP());

Blynk.begin(auth, ssid, password);

while (Blynk.connect() == false) {
// Wait until connected
// Send e-mail when your hardware gets connected to Blynk Server“My_email@address”, “Blynk_test01”, “My Blynk project is online.”); // does not happen …

void loop()
Serial.println(“;”);"", “Blynk_test01”, “My Blynk project is online.”);

// *** WARNING: You are limited to send ONLY ONE E-MAIL PER MINUTE! ***


Sending in loop not recommended. See our examples how to avoid this. Also you may have wrong email or email that filter Blynk email, there are a lot of possible reasons. Try to send to another account for check.

We had an issue recently for newly created users. You have to recreate account. Sorry for inconveniences.
