Hi,
I have gone through the your requirement and found that I can do this task.
I am expert in email Campaign / marketing, deliverability, retention, list cleaning - and growth, Adjust sending Speed per IP/Hour , check our mail reputation etc.
I use various server to send bulk mail like Mailchimp, Sendy, sendgrid, convertkit, Aweber, Sparkpost, Mautic, octopusmail, blueinsending and custom server (SMTP).
I can also design email template for bulk emailing.
Current I am doing same kind of work for my USA, Australia, France, USA, Canada, Europe and Indian based client..
Here i am sending newsletters for various user for my client and make sure they are delivering to there inbox.
Daily I am sending 10000 to 50000 mail as advertisement and newsletter. I am also track unsubscribes, open rate, bounces, and manage the campaigns on a regular basis
Actually bulk mail goes to spam because end user mark them spam in initial stage so we do some test practice to improve deliverance to inbox..
Also we rotate the IP to avoid blacklisted of server and mail.
Best Regards
Ravi
