Current Challenges with Public ESPs
If you’ve been relying on public email service providers (ESPs) like Hotmail, you’ve likely noticed an increase in limitations. Due to recent updates in spam filtering algorithms—particularly by Microsoft—Hotmail accounts can now only send 4 to 10 emails before being blocked. This makes it increasingly difficult to scale cold emailing campaigns.
Temporary Solutions
While some strategies can help mitigate these issues, they may not be sufficient in the long run:
- More Spin Text: Increase variations in your email content to bypass spam filters.
- Diversify Links: Use different URLs in your campaigns to reduce the risk of link-based filtering.
- Try Alternative ESPs: Experiment with other providers like Hotmail PVA, GMX, Mail.ru, or Yahoo.
The Long-Term Solution: Private Domain SMTP
To achieve better deliverability and scalability, consider setting up your own private SMTP server. Here’s a step-by-step guide:
What You Need
- A VPS with Mailing Support
- Virtual Private Servers (VPS) are essential for hosting your email infrastructure. Providers like OVHCloud are a popular choice.
- A Domain
- Ideally, register a .com domain for better credibility.
- Set up domain authentication protocols such as DKIM (DomainKeys Identified Mail). ColdEmailingJet will soon include DKIM setup features, simplifying this process.
- SMTP Server Setup
- Install and configure software like Postfix for sending emails and Dovecot for email retrieval.
- Fiverr can be a great resource to find experts for server setup.
- For paid ColdEmailingJet users (minimum 2 months of subscription), I’m happy to provide assistance.
- Warm-Up Process
- Before sending emails in bulk, you need to warm up your SMTP server. This typically takes around 20 days.
- ColdEmailingJet will soon include an automated warm-up feature, saving you the cost of third-party services.
Private SMTP vs. Free ESPs: Pros and Cons
Free ESPs (e.g., Hotmail, Gmail, Yahoo)
Pros:
- Often have a better inbox rate, as their domains and IPs are highly trusted.
- Easy to use, with user-friendly interfaces.
Cons:
- Strict sending limits (e.g., Hotmail short live accs now only allows only 4-10 emails before blocking).
- Accounts are prone to being flagged or banned for cold emailing.
- Higher cost per email when scaling campaigns due to frequent account replacements.
Private SMTP
Pros:
- Higher sending capacity, with each IP capable of sending at least 5,000 emails daily (some users report up to 50,000 per IP daily).
- Much lower long-term cost compared to free ESPs.
- Full control over the email-sending process, including domain reputation management.
Cons:
- Requires initial setup, including configuring a VPS, domain, and SMTP server.
- Needs a warm-up period of around 20 days to establish a good sender reputation.
- Greater technical knowledge or reliance on external expertise for setup and maintenance.
Why Choose Private SMTP?
- Increased Deliverability: Avoid the sending limits and stricter spam filters of public ESPs.
- Full Control: Customize your email-sending process to meet your specific needs.
- Scalability: Send more emails without worrying about account bans.
