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!

60K/month is roughly 80/hour. Check with your hosting provider which hourly volumes are permitted. Mine allows 250 mails per hour through their server using my email address.

Thanks for sharing that. When you say 250 mails/hour “using your email address,” is that on shared hosting or a VPS/dedicated server? I’m trying to figure out if shared hosting with multiple domains in the panel can realistically handle cold outreach, or if VPS is the safer route.

Also curious - is that 250/hour a global cap across the account, or per domain/email address? I’m planning ~60k/month and want to know if shared hosting throttles everything together or if each domain has its own allowance. From what I’ve seen, shared hosting usually isn’t great for this kind of volume since you’re stuck with strict limits and shared IP reputation.

Also, thanks for recommending Netcup earlier - I’ve started to really like their offers. Do you use any kind of email server setup with them? I’m curious if you’ve tried running mail through their VPS/root servers, and whether shared hosting with domains in the control panel could realistically handle cold outreach, or if VPS/dedicated hosting is the safer route for scaling to around 60k/month.

Do you think it’s better to go with a dedicated IP for cold outreach since with shared IPs I’d basically be at the mercy of whatever other senders are doing? 

The limit of 250 emails per hour applies to a shared hosting plan. That’s 250 emails per domain, which is more than enough for me. I send the emails through Mautic, and they end up in the inbox.

Previously, I used my own SMTP server on a VPS, but unlike the provider’s SMTP server, it has to be gradually warmed up to avoid ending up on spam lists.

Here, too, I use Netcup and am happy with it.
