Best SMTP service for cold emailing (~60k/month)?

Hi everyone,

I recently bought GSA Scrape Genie and plan to use it for cold email outreach. I’m new to this and aiming to send around 60,000 emails per month. My main goal is to maximize inbox placement (not spam or promotions).

I’ve been looking at different SMTP providers and found these options:

• SMTP.com
• SMTP2GO
• Mail250
• Mailgun
• Mailjet
• MailerSend
• Postmark
• Amazon SES
• Elastic Email

Has anyone here used these for cold outreach? Which provider (with dedicated IPs) gives the best chance of landing in the inbox for B2B campaigns? Any experiences, tips, or warnings would be really helpful.

Thanks in advance!
