Key answers
- What is the difference between SPF, DKIM, and DMARC?
- SPF is a DNS TXT record listing which servers may send for your domain. DKIM cryptographically signs each message so receivers can verify it is genuine and unaltered. DMARC builds on both, telling receivers how to handle failures and sending you aggregate reports.
- How do you get marketing email into primary inboxes?
- Configure all three records before your first campaign: add the SPF TXT record (active within about 24 hours), publish the DKIM key pair Bulkit generates, and start DMARC at p=none to monitor before enforcing p=quarantine or p=reject.
Email deliverability is a technical problem that most businesses ignore until their messages start landing in spam. By then, domain reputation has been damaged — sometimes irreparably. The solution is proactive: configure DKIM, SPF, and DMARC before you send your first campaign.
SPF (Sender Policy Framework) tells receiving mail servers which IP addresses are authorized to send on behalf of your domain. Without it, anyone can spoof your address and spam recipients under your brand name.
DKIM (DomainKeys Identified Mail) adds a cryptographic signature to every outgoing message, allowing recipients to verify that the email genuinely came from your domain and was not altered in transit. DMARC builds on both SPF and DKIM to define how receiving servers should handle failures — and sends aggregate reports back to you.
- SPF: Add a TXT record to your DNS — takes 5 minutes, active within 24 hours.
- DKIM: Bulkit generates your public/private key pair and provides the DNS record.
- DMARC: Start with p=none to monitor, then enforce with p=quarantine or p=reject.
- BIMI (Brand Indicators for Message Identification): show your logo in Gmail inboxes.
- Bulkit's email dashboard flags missing DNS records on setup.
Inbox placement is earned, not guaranteed. The businesses that consistently land in primary inboxes are those that treat email authentication as infrastructure — set it up once, maintain it, and monitor aggregate DMARC reports monthly.
Bulkit's email platform walks you through DNS configuration step by step during onboarding. Our team is also available to verify your records and confirm readiness before your first campaign goes live.
