You set up your business email. You can send and receive messages. Everything works—or so you think.
But here's what you don't know: Your emails are going to spam. Your customers aren't receiving your replies. Your professional email address isn't as professional as you think.
This is the reality for over 60% of small businesses: their email setup looks complete, but critical configurations are missing. The result? Lost sales, damaged reputation, and frustrated customers.
The Hidden Email Crisis
Most business owners think email setup is simple: create an address, set a password, start sending. But professional business email requires proper configuration that most developers skip or don't explain.
According to email deliverability research, up to 20% of business emails never reach their destination. They're filtered as spam, blocked by security systems, or rejected by email servers—all because of missing or incorrect email configuration.
The cost? Lost customer inquiries, missed sales opportunities, and damaged business relationships. One study found that businesses with properly configured email see 40% higher response rates than those without.
19 Critical Email Setup Issues You're Probably Missing
1. SPF Record Not Configured
The Problem: SPF (Sender Policy Framework) tells email servers which servers are authorized to send email for your domain. Without it, your emails look suspicious and get marked as spam.
How to Check: Use an SPF checker tool (like mxtoolbox.com) to verify your domain has an SPF record.
How to Fix: Add an SPF record to your domain's DNS settings. Example: v=spf1 include:_spf.google.com ~all (for Google Workspace) or v=spf1 include:mail.yourhosting.com ~all (for hosting-based email).
Impact: Missing SPF can cause 30-50% of your emails to be marked as spam or rejected.
2. DKIM Record Missing
The Problem: DKIM (DomainKeys Identified Mail) cryptographically signs your emails, proving they came from your domain and haven't been tampered with.
How to Check: Send a test email to yourself and check the email headers for DKIM signatures.
How to Fix: Generate DKIM keys from your email provider (Google Workspace, Microsoft 365, or hosting provider) and add them as TXT records in your DNS.
Impact: Without DKIM, email servers can't verify your emails are legitimate, leading to spam filtering.
3. DMARC Policy Not Set
The Problem: DMARC (Domain-based Message Authentication) tells email servers what to do with emails that fail SPF or DKIM checks. Without it, your domain is vulnerable to email spoofing.
How to Check: Use a DMARC checker to see if you have a DMARC policy.
How to Fix: Add a DMARC TXT record. Start with monitoring mode: v=DMARC1; p=none; rua=mailto:[email protected], then move to quarantine or reject after monitoring.
Impact: Missing DMARC leaves you vulnerable to phishing attacks using your domain name, damaging your reputation.
4. Email Forwarding Not Configured
The Problem: You need catch-all forwarding or specific aliases (like info@, sales@, support@) but they're not set up.
How to Check: Send test emails to common addresses (info@, contact@, hello@) and see if they're received.
How to Fix: Configure email forwarding in your email hosting control panel or DNS settings.
Impact: Missing common email addresses means you lose customer inquiries sent to standard addresses.
5. Email Quotas Not Communicated
The Problem: Your email account has storage limits, but you don't know what they are. When you hit the limit, emails bounce back to senders.
How to Check: Check your email account settings for storage limits and current usage.
How to Fix: Set up email archiving, increase storage limits, or regularly clean out old emails.
Impact: Full inboxes cause emails to bounce, making you look unprofessional and losing important communications.
6. No Email Backup System
The Problem: If your email account is compromised or deleted, you lose all your business communications, contacts, and important information.
How to Check: Ask yourself: if my email account disappeared today, what would I lose?
How to Fix: Set up automated email backups using your email provider's tools or third-party backup services. Export important emails regularly.
Impact: Lost emails mean lost business records, customer communications, and potentially legal evidence.
7. Email Client Settings Not Provided
The Problem: You want to use Outlook, Apple Mail, or another email client, but you don't have the IMAP/POP3/SMTP settings.
How to Check: Try setting up your email in a desktop client—do you have all the settings?
How to Fix: Get IMAP/POP3 and SMTP settings from your email provider. Document them for future reference.
Impact: Without proper settings, you're stuck using webmail, limiting your productivity and email management options.
8. Two-Factor Authentication Not Enabled
The Problem: Your email account is protected only by a password, making it vulnerable to hacking.
How to Check: Check your email account security settings for 2FA status.
How to Fix: Enable two-factor authentication in your email account settings. Use an authenticator app (Google Authenticator, Authy) for better security.
Impact: Compromised email accounts can lead to identity theft, business email compromise (BEC) scams, and data breaches.
9. Professional Email Signatures Not Set Up
The Problem: Your emails don't have professional signatures with your contact information, branding, or legal disclaimers.
How to Check: Send yourself a test email—does it have a professional signature?
How to Fix: Create email signatures in your email client or email provider settings. Include name, title, company, phone, website, and any required legal disclaimers.
Impact: Missing signatures make emails look unprofessional and make it harder for recipients to contact you through other channels.
10. Email Routing Issues
The Problem: Emails are going to the wrong inboxes, not forwarding properly, or getting lost in routing.
How to Check: Test email routing by sending to different addresses and checking where they arrive.
How to Fix: Review email forwarding rules, aliases, and routing settings. Ensure all business emails route to the correct inboxes.
Impact: Misrouted emails mean lost customer inquiries, delayed responses, and frustrated customers.
11. Email Deliverability Not Tested
The Problem: You assume your emails are being delivered, but you've never actually tested deliverability to major email providers.
How to Check: Use email deliverability testing tools (like Mail Tester, GlockApps) to test your email setup.
How to Fix: Test email deliverability regularly. Send test emails to Gmail, Outlook, Yahoo, and other major providers to ensure they arrive in the inbox, not spam.
Impact: Poor deliverability means your marketing emails, invoices, and important communications never reach recipients.
12. Email List Not Connected to Website
The Problem: Your website has newsletter signup forms, but they're not connected to your email marketing platform.
How to Check: Test your newsletter signup form—does it actually add subscribers to your list?
How to Fix: Connect your website forms to your email marketing platform (Mailchimp, Constant Contact, etc.) using API keys or integration tools.
Impact: Disconnected forms mean lost leads and missed marketing opportunities.
13. Auto-Responders Not Configured
The Problem: When customers email you, they don't get confirmation that you received their message.
How to Check: Send a test email to your business address—do you get an auto-reply?
How to Fix: Set up auto-responders for common scenarios: out-of-office, inquiry confirmations, support ticket acknowledgments.
Impact: Missing auto-responders leave customers wondering if their email was received, leading to duplicate inquiries and frustration.
14. Email Spam Filtering Not Configured
The Problem: Your inbox is flooded with spam, or legitimate emails are being filtered as spam.
How to Check: Review your spam folder regularly—are legitimate emails ending up there?
How to Fix: Configure spam filtering rules, whitelist important senders, and train your spam filter by marking emails correctly.
Impact: Poor spam filtering means you miss important emails or waste time sorting through spam.
15. Email Archiving Not Set Up
The Problem: Old emails pile up, filling your inbox and making it hard to find important messages.
How to Check: How many emails are in your inbox? Can you easily find emails from 6 months ago?
How to Fix: Set up email archiving rules to automatically move old emails to archive folders. Use email search and organization tools.
Impact: Unorganized email makes you less productive and increases the risk of missing important communications.
16. Email Encryption Not Enabled
The Problem: Sensitive business emails are sent in plain text, vulnerable to interception.
How to Check: Check if your email provider offers encryption (TLS/SSL for transmission, end-to-end encryption for storage).
How to Fix: Enable email encryption in your email provider settings. Use encrypted email services for highly sensitive communications.
Impact: Unencrypted emails can be intercepted, exposing sensitive business information and customer data.
17. Email Bounce Handling Not Monitored
The Problem: When emails bounce (can't be delivered), you don't know about it, so you keep sending to invalid addresses.
How to Check: Review your email logs for bounce messages and invalid addresses.
How to Fix: Set up bounce handling to automatically remove invalid addresses from your mailing lists. Monitor bounce rates regularly.
Impact: High bounce rates damage your sender reputation, causing more emails to be marked as spam.
18. Email Domain Reputation Not Monitored
The Problem: Your domain's email reputation is poor, but you don't know it until emails start getting blocked.
How to Check: Use email reputation monitoring tools (like Sender Score, BarracudaCentral) to check your domain's reputation.
How to Fix: Monitor your email reputation regularly. Maintain good sending practices: don't spam, clean your lists, authenticate properly.
Impact: Poor reputation means your emails are blocked or filtered as spam, even if your content is legitimate.
19. Email Migration Plan Not Documented
The Problem: If you need to change email providers or hosting, you don't have a plan for migrating emails and maintaining continuity.
How to Check: Do you have documentation of your email setup? Do you know how to migrate if needed?
How to Fix: Document your email configuration, create a migration plan, and test email migration procedures before you need them.
Impact: Poor migration planning can cause email downtime, lost emails, and business disruption.
The Cost of Missing Email Configuration
These aren't minor issues. The cost of poor email setup is real:
- Lost sales: 20-30% of business emails never reach customers, meaning lost inquiries and sales
- Damaged reputation: Emails going to spam make you look unprofessional
- Security risks: Missing authentication leaves you vulnerable to phishing and spoofing attacks
- Compliance issues: Poor email security can violate GDPR and other regulations
- Productivity loss: Unorganized email and spam waste hours every week

Frequently Asked Questions
What is SPF and why do I need it?
SPF (Sender Policy Framework) is a DNS record that tells email servers which servers are authorized to send email for your domain. Without SPF, email servers can't verify your emails are legitimate, causing them to be marked as spam or rejected. SPF is essential for email deliverability—without it, 30-50% of your emails may never reach their destination.
How do I check if my email is going to spam?
Use email deliverability testing tools like Mail Tester (mail-tester.com) or GlockApps. Send a test email to the provided address, and the tool will analyze your email setup, SPF/DKIM/DMARC configuration, and spam score. You can also send test emails to Gmail, Outlook, and Yahoo accounts and check if they arrive in the inbox or spam folder.
What's the difference between SPF, DKIM, and DMARC?
SPF lists which servers can send email for your domain. DKIM cryptographically signs your emails to prove they're authentic and haven't been tampered with. DMARC tells email servers what to do with emails that fail SPF or DKIM checks. All three work together: SPF and DKIM authenticate your emails, and DMARC provides policy enforcement. You need all three for proper email security and deliverability.
How often should I test my email deliverability?
Test email deliverability when you first set up your email, after making any DNS changes, and monthly as part of regular maintenance. Also test immediately if you notice emails aren't being received or are going to spam. Regular testing helps catch configuration issues before they become serious problems.
Can I set up SPF/DKIM/DMARC myself?
Yes, if you have access to your domain's DNS settings and understand how to add DNS records. Your email provider (Google Workspace, Microsoft 365, or hosting provider) will provide the exact records you need. However, incorrect configuration can break email delivery, so it's often safer to have a professional handle it. Our website development service includes proper email configuration.
What happens if I don't set up email authentication?
Without SPF, DKIM, and DMARC, your emails are much more likely to be marked as spam or rejected by email servers. Your domain is also vulnerable to email spoofing, where attackers send emails that appear to come from your domain. This can damage your reputation, lead to phishing attacks against your customers, and cause your legitimate emails to be blocked. Proper email authentication is essential for business email.
