Setting up your email infrastructure is the most important step before diving into cold emailing. A well-planned infrastructure ensures that your emails are delivered to the inbox, not flagged as spam, and that your sender reputation remains strong. Here's what I practice and recommend:
- Choosing a Domain
Instead of using your main domain (e.g., yourcompany.com), get a few lookalike domains that resemble your business/service. This reduces the risk to your primary domain’s reputation. Services like Maildoso offer affordable domains and email accounts.
Note: Avoid free email services like Gmail or Outlook for cold emailing as they’re more likely to be flagged as spam.
- Implement Email Authentication:
Set up SPF, DKIM, and DMARC records to improve your email deliverability. These protocols ensure that your emails are authenticated.
If you’re not sure how to set these up, consult with your IT team or an email deliverability expert. If you're purchasing email services from Maildoso, they will take care of these settings for you, so you don’t have to worry about them.
- Create Email Accounts
Set up 4 to 5 email accounts per domain, with each account sending around 30-50 emails/day. This volume is a safe starting point to avoid being flagged as a spammer.
- Warm Up Your Email Accounts
Warm up your email accounts for 15 to 20 days. Tools like Warmup Inbox and Lemwarm offer warm-up services.
(Tip: Instantly provides free warm-up services for unlimited accounts, but the volume is lower compared to other paid tools.)
- Warm-Up to Actual Email Ratio
If you're warming up an account by sending 10 emails a day, limit your actual cold emails to no more than 3 times that amount
- Bonus Tip:
Keep Your First Email Simple
Avoid using hyperlinks, images, or too much information in your first email. Plain-text emails are less likely to get flagged by spam filters and often see better engagement.
