Best Practices to Improve Email Deliverability in Zoho Recruit

Configure your SMTP server details (for example Office 365) under Email Relay in settings, send a test email to confirm it goes via your own IP, and once confirmed all outbound email will use the relay.

3. Warm up your email domain: avoid bulk sending from a fresh domain or IP. Send small volumes initially, monitor bounce, open and reply rates, and gradually increase volume over a few weeks.

Tips

• Keep your email list clean by removing invalid, inactive or unsubscribed contacts, and aim for a bounce rate below 2%.
• Use double opt-in to confirm subscribers before adding them, reducing typos and fake addresses.
• Avoid spammy content, such as excessive capital letters, exclamation marks or “Buy now” style phrases.
• Segment your communications, for example by job role or industry, to keep messages relevant.
• Monitor sender reputation using SPF, DKIM and DMARC checkers, and review bounce reports regularly.
• Set up a custom return path (CNAME) to reduce spoofing and align SPF, which helps inbox placement.

Frequently asked questions

What is the golden standard for email authentication?

SPF and DKIM prove your emails are genuine, and adding DMARC on top is considered the gold standard for email authentication.

Why should I warm up a new sending domain?

Sending a large volume of email from a brand-new domain or IP can trigger spam filters. Warming up gradually builds trust with mail providers.

What bounce rate should I aim for?

Aim to keep your bounce rate below 2 percent by regularly removing invalid, inactive or unsubscribed contacts.
