If you’re using Zoho Mail and struggling with low open rates, emails landing in spam, or warnings about authentication, SPF and DKIM are not optional anymore - they’re essential.

[ Discover DKIM Selectors → ](/tools/dkim-lookup/) DKIM ([RFC 6376](https://datatracker.ietf.org/doc/html/rfc6376)) signs email messages cryptographically, and unlike SPF, the signature survives email forwarding - which is why DMARC alignment via DKIM is more reliable than SPF alignment for forwarded mail. > DKIM is the authentication protocol that survives email forwarding, says Brad Slavin, General Manager of DuoCircle. When SPF fails because a forwarder’s IP isn’t in the original record, DKIM alignment is the only path to DMARC pass. That’s why we monitor DKIM alongside SPF in every DMARC Report dashboard. Email is still the backbone of business communication - but only when your messages actually reach the inbox. If you’re using Zoho Mail and struggling with low open rates, emails landing in spam, or warnings about authentication, \*\*SPF and DKIM are not optional anymore - they’re essential. At DMARCReport, we work with organizations every day to fix email deliverability issues and protect domains from [spoofing and phishing](https://www.scworld.com/brief/fbi-us-officials-spoofed-in-ongoing-voice-sms-phishing-campaign). One of the most common problems we see? SPF and DKIM records that are missing, misconfigured, or never properly verified. In this guide, we’ll walk you through \*\*how to set up SPF and DKIM \*\*for Zoho Mail step by step, using clear language and practical examples - no deep technical background required. ## Why SPF and DKIM Matter for Zoho Mail Before jumping into setup, it helps to understand _why_ these records matter. \*\*Email providers like Gmail, Outlook, and Yahoo want proof that: - You’re allowed to send email from your domain - Your messages haven’t been altered in transit - You’re not impersonating someone else That’s where SPF and DKIM come in. ![How to create dmarc record](https://media.mailhop.org/dmarcreport/images/2026/01/how-to-create-dmarc-record-5876.jpg) ## What Is SPF? **SPF (Sender Policy Framework)** tells receiving [mail servers](https://www.cloudflare.com/learning/email-security/what-is-a-mail-server/) which email services are authorized to send email on behalf of your domain. When you send an email from Zoho Mail, the recipient’s server checks your SPF record. If Zoho is listed as an approved sender, the email passes SPF. If not, the message may be flagged as spam - or rejected entirely. ## What Is DKIM? **DKIM (DomainKeys Identified Mail)** adds a [digital signature](https://en.wikipedia.org/wiki/Digital%5Fsignature) to your outgoing emails. This signature allows receiving servers to verify that: - The email really came from your domain - The content wasn’t modified after it was sent SPF validates _where_ the email came from. \*\*DKIM validates what was sent. Together, they build trust. ## What You Need Before Getting Started To configure SPF and DKIM for Zoho Mail, you’ll need: - Access to your domain’s DNS manager (usually through your domain registrar or hosting provider) - Admin access to Zoho Mail - A little patience - DNS changes can take time to propagate No coding or \*\*advanced networking knowledge required. ## How to Set Up SPF for Zoho Mail ## Step 1: Check If You Already Have an SPF Record Most domains already have an SPF record - especially if you use multiple email tools. Log in to your DNS manager and look for a [TXT record](https://www.digicert.com/faq/dns/what-is-a-txt-record) that starts with: v=spf1 If you find one, **do not create a second SPF record**. Having multiple SPF records breaks authentication. Instead, you’ll update the existing one. ## Step 2: Add Zoho to Your SPF Record Zoho Mail requires the following SPF mechanism: include:zoho.com ## If You Don’t Have an SPF Record Create a new TXT record with: v=spf1 include:zoho.com \~all - \~all means “soft fail” and is **recommended for beginners** # ## If You Already Have an SPF Record Simply add include:zoho.com inside the existing record, like this: v=spf1 include:zoho.com include:spf.google.com \~all Make sure: - There is **only one SPF record** \- The record stays under the 10 [DNS lookup](https://www.ibm.com/think/topics/dns-lookup) limit ## Step 3: Save and Wait for DNS Propagation _DNS updates can take anywhere from a few minutes to 48 hours_. Once saved, Zoho Mail will start authenticating messages using SPF. ![Dmarc check](https://media.mailhop.org/dmarcreport/images/2026/01/dmarc-check-5862.jpg) ## How to Set Up DKIM for Zoho Mail SPF alone isn’t enough for **strong email authentication**. DKIM adds an extra layer of credibility - and many inbox providers now expect it. ## Step 1: Generate a DKIM Record in Zoho Mail - Log in to Zoho Mail Admin Console - Go to Domains → Select your domain - Click DKIM → Add DKIM Record - Choose a selector name (Zoho may suggest one) - Generate the DKIM key Zoho will provide: - A TXT record name (host) - A \*\*TXT record value \*\*(DKIM public key) ## Step 2: Publish the DKIM Record in DNS Go to your DNS manager and create a new TXT record using the values Zoho provides. Important tips: - Copy the value exactly - no extra spaces - If the key is long, make sure your DNS provider \*\*supports long TXT records ## Step 3: Verify DKIM in Zoho Once the record is added: - Return to Zoho Mail Click Verify next to your [DKIM record](https://dmarcreport.com/blog/what-is-dkim-record-guide-setup-mistakes-and-dmarc-alignment/) If verification fails, don’t panic. Common causes include: - [DNS propagation](https://www.networksolutions.com/blog/what-is-dns-propagation/) delay - **Incorrect formatting** \- Using the wrong selector Wait a little and try again. ## What Are Common SPF and DKIM Mistakes to Avoid? At DMARCReport, we see these issues repeatedly: ## Multiple SPF Records This is the #1 SPF error. \*\*Always combine mechanisms into a single record. ## Forgetting Other Email Tools If you use services like: - [Marketing platforms](https://www.indeed.com/career-advice/career-development/what-is-a-marketing-platform) - Support ticket systems - Transactional email tools _They must also be included in your SPF record_. ## DKIM Not Enabled for All Domains If you have \*\*multiple domains or subdomains in Zoho Mail, each one needs DKIM configured separately. ![Dmarc record](https://media.mailhop.org/dmarcreport/images/2026/01/dmarc-record-6832.jpg) ## How SPF and DKIM Support DMARC SPF and DKIM are the foundation of DMARC (Domain-based Message Authentication, Reporting, and Conformance). DMARC allows you to: - Tell receiving servers what to do when authentication fails - Get visibility into who is sending email on your behalf - \*\*Protect your domain from spoofing and phishing Without [SPF](https://dmarcreport.com/what-is-spf/) and [DKIM](https://dmarcreport.com/what-is-dkim/) in place, DMARC simply won’t work. Once both are configured and passing , you can safely move toward a DMARC policy that actively protects your domain. ## How DMARCReport Helps After Setup Configuring SPF and DKIM is only the beginning. With [DMARCReport](http://dmarcreport.com/), you can: - Monitor SPF and DKIM pass/fail results - Identify unauthorized senders - Simplify \*\*complex DMARC reports into readable insights - Improve inbox placement over time [Email authentication](https://www.emailtooltester.com/en/blog/email-authentication/) isn’t a one-time task - it’s an ongoing process. ## Final Thoughts _Setting up SPF and DKIM for Zoho Mail doesn’t have to be complicated_. With the right steps - and a clear understanding of what these records do - you can significantly \*\*improve email deliverability and protect your [brand’s reputation](https://www.cision.com/resources/insights/brand-reputation/). At DMARCReport, we recommend: - Configure SPF correctly (one record, all senders included) - Enable DKIM for every sending domain Monitor performance and evolve toward DMARC enforcement Inbox trust is earned - and SPF and DKIM are where it starts.
