Tips to Boost Your Email Deliverability
Even if you are using the best SMTP server provider, your emails will not reach the inbox without following good email practices. Email deliverability depends on how trusted your sender identity is and how users interact with your emails. Below are some easy and effective tips to improve your email deliverability.
- Authenticate Your Domain
Email authentication is very important. Always set up SPF, DKIM, and DMARC records for your domain. These records tell email providers that your emails are genuine and not spam. Proper authentication builds trust and protects your domain from misuse. - Warm-Up Your IP Address
Do not send a large number of emails suddenly from a new IP. Start with a small volume and slowly increase it over time. This process is called IP warm-up and helps build a good sender reputation with email providers. - Keep Your Email List Clean
Sending emails to invalid or inactive email addresses can damage your sender reputation and reduce email deliverability. Regularly remove bounced emails, fake addresses, and users who never open your emails. A clean list improves open rates and reduces spam complaints. - Monitor Email Engagement
Always track how users interact with your emails. Check open rates, click rates, bounces, and spam complaints. Low engagement signals can hurt deliverability. Use analytics to improve subject lines, content, and sending time. - Send Relevant Content
Send emails that users actually want to read. Avoid spammy words and misleading subject lines. Relevant content keeps users engaged and reduces unsubscribes. - Be Consistent with Sending
Maintain a regular sending schedule. Sudden spikes or long gaps in email activity can raise red flags for email providers.
