Here's what I use for cold email outreach for my performance marketing services.
- I have purchased a few domains from GoDaddy similar to my business name, and for each domain, I have about 5 email addresses. I prefer GoDaddy as there's no need to set up DKIM, SPF, and DMARC. For 3000 emails, you will need 10 accounts, and you can send and schedule 25 emails each day (one email every 9-10 minutes) from one email address.
- Warm up your email accounts for 10 days at least to ensure your emails are not ending up in spam.
- Personalize your emails as much as possible to achieve a higher open rate and improved deliverability.
- Always verify the email addresses through a verification service to ensure your emails are not bouncing up.
Here's what I wouldn't do.
- I wouldn't use Gmail for outreach. People may not take your offer seriously when they see you are sending it from Gmail.
- I wouldn't use emails linked to my business domain, as when you outreach, people mark your email as spam. You don't want your important business email landing up in spam.
