Your domain’s DNS (Domain Name System) records are the unsung heroes behind every successful cold email campaign. Whether you're just getting started or scaling up, setting these up correctly is critical for maximizing email deliverability, trust, and performance inside Coldbean.
This guide explains why DNS records matter, how they relate to Coldbean, and what you need to do next.
The Role of DNS in Coldbean's Email Delivery
Does Coldbean Send the Emails Directly?No. Coldbean doesn’t send emails from its own servers. Instead:
Coldbean schedules, personalizes, tracks, and sequences your campaigns.
The actual email delivery is done through your connected email service provider (ESP) like Google Workspace or Microsoft Outlook.
Coldbean passes the email content and metadata to your ESP, which uses your DNS records to authenticate and deliver the message.
Why DNS Records Are So ImportantEven though Coldbean doesn’t require SPF/DKIM/DMARC, your ESP absolutely does.
These DNS records tell receiving email servers, “Hey, this message is legit and authorized by this domain.”
| Record Purpose |
SPF | Confirms which servers can send emails for your domain |
DKIM | Adds a digital signature to verify the content hasn't been tampered with |
DMARC | Provides instructions on how to handle failed SPF/DKIM checks + reporting |
Without these, your emails are more likely to land in spam — or be rejected entirely.
What Coldbean Actually HandlesHere’s what happens behind the scenes:
Campaign Logic: Coldbean prepares your content and follow-up logic.
Timing: Coldbean schedules sends for optimal delivery.
Rotation: Coldbean may rotate sending accounts or track IPs.
Tracking: Coldbean injects tracking pixels and handles analytics.
But all of this relies on your sending domain’s reputation, which is built on strong DNS configuration.
Choosing and Preparing Email AccountsTo start using Coldbean, we recommend setting up mailboxes from trusted providers:
