How to buy domains and email accounts for your cold email campaigns
If you want to run cold email campaigns professionally, at scale, and without constantly landing in spam folders, there is one important thing you need to understand:
The success of your campaigns does not depend only on the message you send, but also on the technical infrastructure behind it.
One of the most common mistakes beginners make is using their personal Gmail or Outlook account and immediately starting to send hundreds of emails per day from it.
For example:
And then sending 100, 200, or 300 cold emails per day from a single account.
What happens when you do this?
Email providers such as Google and Microsoft quickly detect suspicious behavior.
When an account starts sending too many cold emails in a short period of time:
- Its reputation decreases
- Emails start landing in spam folders
- Open rates drop
- Reply rates decrease
- In some cases, the account may become restricted
This is why professional cold email works differently.
The Right Way to Send Cold Emails
The key is to distribute your sending volume across multiple email accounts and domains.
Instead of sending 150 emails per day from a single account, you spread the volume across several accounts to maintain a healthy sender reputation.
Practical Example
Imagine you want to send approximately:
- 150 emails per day
A recommended setup would look something like this:
Domains | Accounts per Domain | Total Accounts |
|---|---|---|
3 domains | 3 accounts each | 9 accounts |
If each account sends:
- 10–15 emails per day initially
- 20–30 emails per day once warmed up
You can scale your outreach without compromising deliverability.
How Many Emails Can Each Account Send?
As a general guideline:
Account Status | Recommended Sending Volume |
|---|---|
New account | 10–15 emails/day |
Warmed-up account | 20–30 emails/day |
Trying to send too many emails from a brand-new account is one of the main reasons emails end up in spam.
Learn the Fundamentals Before Scaling
Inside the Mailerfind Academy, you'll find the Technical Setup training, where we explain in depth:
- How to avoid landing in spam
- How domains work
- What account warm-up is
- How to properly configure your infrastructure
- How to improve deliverability
- How to scale campaigns safely
Understanding this technical side can make a huge difference in your campaign results.
Purchasing Domains and Email Accounts in Mailerfind
Mailerfind allows you to:
- Connect your own email accounts manually
- Or let our system handle the entire technical setup automatically
The second option is highly recommended if you want to save time and avoid complex configurations.
Step 1 — Access the Email Accounts Section
Inside Mailerfind, navigate to:
Email Accounts
Here you'll find two options:
- Connect accounts manually
- Purchase accounts automatically through Mailerfind
Select:
Purchase Accounts
Step 2 — Select Your Email Provider
Currently, we recommend using:
- Google Workspace
This allows you to work with professional-grade email infrastructure and improve your campaign deliverability.
Step 3 — Choose Your Domains
A domain is the name associated with your brand.
For example:
With Mailerfind, you can:
- Search for available domains
- Add multiple extensions
- Purchase several domains in a single order
Important Recommendation
Don't use only your primary domain.
For example, if your company domain is:
It's recommended to use variations specifically for cold email, such as:
This helps protect the reputation of your primary domain.
Step 4 — Configure Your Mailboxes
Once your domains have been added, you can create mailboxes for each one.
For example:
Domain | Mailboxes |
|---|---|
3 | |
3 | |
3 |
Total:
- 3 domains
- 9 email accounts
With this infrastructure, you can safely send approximately:
- 100–200 emails per day
depending on the warm-up status and reputation of your accounts.
Step 5 — Review the Summary and Complete Payment
Before finalizing your order, you'll see:
- Number of domains
- Number of mailboxes
- Total cost
After that, simply:
- Enter the required domain registration details
- Complete the payment
Mailerfind will automatically:
- Purchase the domains
- Create the email accounts
- Configure the technical infrastructure
- Add the mailboxes to your account
Step 6 — Start Sending Campaigns
Once the accounts are configured, they will appear under:
Email Accounts
From there, you can use them in your cold email campaigns inside Mailerfind.
Final Recommendations
Don't Scale Too Fast
Patience is key.
A properly warmed-up infrastructure can remain effective for months or even years.
Prioritize Quality Over Volume
It's better to:
- Send 100 emails with strong deliverability
than to:
- Send 1,000 emails that end up in spam.
Use Multiple Domains
This reduces risk and improves the stability of your campaigns.
Always Warm Up New Accounts
Never start sending large volumes from newly created accounts.
Conclusion
Most cold email problems are not caused by the copy or the offer.
They are caused by poor technical infrastructure.
If you properly configure:
- Domains
- Email accounts
- Account warm-up
- Sending volume
You'll be able to build scalable and sustainable cold email campaigns without relying on ads or constantly fighting spam filters.
