Will your emails always arrive?
Monitor your MX, SPF, DKIM and DMARC records, and blacklist status. Get alerted when something changes or breaks.
Email authentication is invisible until it breaks. A misconfigured SPF record, an expired DKIM key, or landing on a blacklist can send your emails straight to spam — or block them entirely. Email Deliverability Suite checks your records daily and alerts you the moment something needs attention.
Free for up to 3 domains. $39/mo for unlimited.
Start monitoring →Built for SPF Records
SPF Creator is a dedicated SPF record generator with features designed specifically for building correct, optimized SPF records.
Real-Time DNS Lookup Counter
The #1 reason SPF records break is exceeding the 10 DNS lookup limit. SPF Creator counts lookups as you add providers — before you publish. No more guessing whether your record is valid.
20+ Provider Presets
Google Workspace, Microsoft 365, SendGrid, Mailchimp, Amazon SES, and more. One click adds the correct include with accurate lookup cost.
100% Client-Side
Your SPF record is generated locally in your browser. No data is sent to any server. No account required. No tracking.
Instant Validation
Syntax errors, duplicate includes, and lookup overflows are caught before you copy the record. Build with confidence.
Email Deliverability Suite
Ongoing Monitoring
After you create your SPF record, monitor it alongside DKIM, DMARC, MX, and blacklist status.
SPF Record Monitoring
Your SPF record tells mail servers which IPs can send email for your domain. Email Deliverability Suite monitors your SPF record for changes and tracks your DNS lookup count — exceeding the 10 lookup limit silently breaks authentication.
What we check:
- Record changes
- DNS lookup count (10 limit)
- Syntax validity
- Missing or deleted records
DKIM Record Monitoring
DKIM proves your emails haven't been tampered with in transit. Email Deliverability Suite monitors your DKIM keys and alerts you if they change, disappear, or become invalid.
What we check:
- Record changes
- Key presence
- Key validity
- Selector configuration
DMARC Policy Monitoring
DMARC tells receiving servers what to do when SPF or DKIM fails. Email Deliverability Suite monitors your DMARC policy and alerts you to changes that could affect how failed emails are handled.
What we check:
- Policy changes
- Record validity
- Subdomain policy
- Reporting configuration
MX Record Monitoring
MX records route incoming email to your mail servers. Email Deliverability Suite monitors for changes that could break inbound email delivery.
What we check:
- Record changes
- Mail server resolution
- Priority configuration
- Missing records
Blacklist Monitoring
Landing on an email blacklist can tank your deliverability overnight. Email Deliverability Suite checks major blacklists daily and alerts you immediately if your domain or sending IPs get listed.
What we check:
- Spamhaus (SBL, XBL, PBL, DBL)
- Barracuda
- SpamCop
- SORBS
- Other major blacklists
