EmailControl monitors your business email domains for spam blacklisting and authentication failures, alerting you before deliverability drops.

The most common causes are a compromised mailbox sending spam, a shared server IP with a bad neighbor, missing SPF/DKIM/DMARC authentication, high bounce rates from stale mailing lists, and spam complaints from recipients. Blacklist operators like Spamhaus and Barracuda detect these signals automatically and can list your sending IP within hours.

You query DNS-based blacklists (DNSBLs) with your mail server's IP address reversed against each blacklist zone. EmailControl automates this: it resolves your domain's MX record, checks the IP against Spamhaus ZEN, Barracuda, SORBS, and SpamCop on a schedule, and emails you the moment a listing appears.

They are DNS records that prove your email is legitimate. SPF lists the servers allowed to send for your domain. DKIM adds a cryptographic signature to each message. DMARC tells receiving servers what to do when SPF or DKIM fails — none, quarantine, or reject. Mailbox providers increasingly require all three.

Publish a TXT record at _dmarc.yourdomain.com starting with v=DMARC1 and a valid p= policy tag, for example: v=DMARC1; p=quarantine; rua=mailto:reports@yourdomain.com. Most failures come from a missing p= tag, a typo in the record, or publishing it at the wrong hostname. EmailControl shows your current record and a plain-language fix.

Free plans are checked weekly, Pro plans daily, and Agency plans hourly. Every plan can also trigger a manual check from the dashboard (limited to one per domain per hour).

No. EmailControl is monitoring and alerting only — it never sends mail through your domain or connects to your mail server. It reads public DNS records and blacklist zones, the same way receiving mail servers do.

No — EmailControl is advisory. It detects problems and gives you the exact record to publish, but you (or your DNS provider) make the change. This keeps your DNS credentials out of third-party hands.

A score of 80–100 (green) means you are clean on all monitored blacklists with valid SPF, DKIM, and DMARC. 50–79 (amber) usually means a weak DMARC policy or a missing record. Below 50 (red) almost always means an active blacklist listing — act immediately.

First fix the root cause — a compromised account, an open relay, or a bad list — otherwise you will be relisted. Then submit a removal request through the Spamhaus Blocklist Removal Center. Most legitimate delisting requests process within 24–48 hours. EmailControl alerts you when the delisting takes effect.

No. You add a domain and EmailControl handles the DNS queries. Every failing check comes with a plain-language explanation and copy-paste fix suggestion. If you can edit a DNS record at your registrar, you can fix everything we flag.
