We have developed an email marketing software that requires us to send out about 10,000 emails a day (and more in coming weeks as we try to scale).
We tried sending it with gmail, yahoo and hotmail accounts using their own SMTP server but they get blocked.
We tried sending emails using Sendgrid and SMTP.com - servers but their IP gets blocked as well.
We tried pausing/delaying the delivery and not send out more than 5 or 10 emails per hour from 1 account . That also didn't work
We need help from someone who is expert in email delivery, and configure email server and help us send out emails.
