Send more than 10 lakh emails from Mautic

Your software
My Mautic version is: 2.15.1
My PHP version is:5.6 and 7

Your problem
My problem is:
Suppose, I need to send more than 10 lakh emails from my Mautic platform. ( I have around 35000 contacts & campaign triggering will occur for 10 lakh email deliveries) Currently PHP Mailer has been configured. Can i achieve it by setting the cron job with Queuing delivery? Or if any other mailer like Sendgrid, Gmail, Sendmail, Sparkpost,etc. can achieve the same? Have you dealt with this earlier? if any server setup is particularly required, kindly let us know. Please provide your support for the same.
