A website that I used my password on was compromised and the monkeys in charge had stored everything in plaintext. The list was released publicly online. Needless to say, my password and email were among them.
I would like to send emails to everyone else who was listed (thousands) and inform them that to continue using their password is unsafe. My language of choice would be C# and I would be sending them from my gmail with the help of this code: Sending email in .NET through Gmail
I can pretty much assume gmail will lock me out before I finish 10 in under a minute. Apart from sending emails out intermittently, how can I do this?
edit: I agree with the responses. I should instead send one email. Is there a limit to the amount of recipients I send an email to from gmail?
If happy to spend a bit of money for a reliable solution, you could integrate (very easily) with http://sendgrid.com. Provides you with heaps of features to track delivery of email and reporting/analysis of email opening, clicking etc.
Gmail does have limitations on how many emails you can send per day, and I would not recommend for your usage.
