Setting up an email domain is often frustrating. Nearly 20% of business emails never reach the inbox due to poor authentication and misconfigured DNS settings. SPF, DKIM, and DMARC are essential for deliverability, yet a majority of domains lack proper authentication.  

Many businesses struggle with these technical steps, leading to wasted time and lost opportunities. With SmartSenders, you can buy an email domain and mailboxes with automatic setup—no manual configuration needed. Everything is pre-configured for optimal security and deliverability. 

In this guide, we’ll show you how to purchase domains and mailboxes effortlessly with SmartSenders, ensuring your emails reach the inbox every time.

Why Buying the Right Email Domain Matters for Your Business

Your email domain plays a crucial role in determining whether your emails land in the inbox or get flagged as spam. Internet Service Providers (ISPs) and spam filters evaluate your domain’s reputation before delivering emails. If your domain lacks proper authentication records or has a history of spammy behavior, your emails are more likely to be blocked.

A strong domain reputation improves deliverability, ensuring that your outreach reaches the intended recipients. According to a study by Validity, only 83% of marketing emails reach the inbox, with the rest landing in spam or being rejected entirely due to authentication failures and poor domain reputation.

Common Mistakes While Setting Up Email Accounts 

Setting up an email domain incorrectly can harm deliverability, security, and brand reputation. Here are some of the most common mistakes, backed by data and expert insights: 

1. Not Setting Up SPF, DKIM, and DMARC Properly

SPF (Sender Policy Framework): Email providers can’t verify if an email sent from your domain is legit without an SPF record. This increases the risk of emails landing in spam folders.

DKIM (DomainKeys Identified Mail): A missing or misconfigured DKIM signature means your emails can be tampered with in transit, reducing trust.

DMARC (Domain-Based Message Authentication, Reporting & Conformance): Without a DMARC policy, your domain is vulnerable to spoofing and phishing attacks. A properly set DMARC policy can reduce phishing attempts by 77%. 

2. Using a Domain with a Bad Reputation

If your domain has been previously flagged for spam, email providers will automatically distrust emails from it. Gmail's Postmaster Tools assess domain reputation, and a poor score can significantly lower inbox placement rates, which can lead to your emails landing in spam and eventually getting domain blocked.   

3. Ignoring IP Reputation Issues

Your sending IP can be on a blocklist if previous emails from it were flagged as spam. Using shared IPs with bad senders affects your reputation, which is why choosing the right ESP is crucial. A trusted ESP with a high IP reputation can improve inbox placement rates.

4. Not Monitoring Email Complaints and Spam Reports

If recipients repeatedly mark your emails as spam, it damages your sender reputation. Gmail's Postmaster Tools show spam complaint rates, and a high rate can cause future emails to be automatically filtered into spam.

5. Failing to Keep a Clean Email List

Sending emails to inactive or unengaged users increases bounce rates and complaints. Spammers often use outdated or purchased email lists, and mailbox providers penalize domains with poor email list hygiene.

Many businesses unknowingly harm their email deliverability by making these mistakes:

1. Skipping SPF, DKIM, and DMARC setup – Without these authentication records, your emails can be spoofed, increasing spam risk.
2. Using free email domains (e.g., Gmail, Yahoo) for business outreach – This lowers credibility and limits control over email deliverability.
3. Overusing a single domain for bulk email campaigns – Sending too many emails from one domain can lead to reputation damage and blacklisting.
4. Not warming up new domains – New domains lack sending history, so sudden high-volume emails can trigger spam filters.
