The short answer
- Choose EmailGuard if you want one tool for inbox placement tests with seed accounts, contact verification, hosted redirects and DMARC, and weekly domain checks are enough.
- Choose EmailHealth if your main problem is domains that break without anyone noticing, and you want a daily check of every domain with an alert that says exactly what to change.
- Many teams can use both: a placement-testing tool for campaigns, and daily monitoring for the domains under them.
How often domains are checked
EmailGuard's pricing page lists weekly automated blacklist checks and weekly automated SPF, DKIM and DMARC checks, plus unlimited checks you run by hand. EmailHealth checks every monitored domain every day.
The difference matters for secondary domains. A DNS move that drops the DKIM record, a second SPF record added by mistake, or a new blocklist listing can stop a campaign within hours. With a weekly check, mail from that domain can bounce or go to spam for several days before anyone sees it.
Side by side
| EmailGuard | EmailHealth | |
|---|---|---|
| Automatic domain checks | Weekly (blacklists, SPF, DKIM, DMARC) | Daily (MX, SPF, DKIM, DMARC, blocklists, TLS, MTA-STS, DNS changes, domain expiry) |
| Alert channels | Not listed on its pricing page | Email, Slack and signed webhooks, one alert per change |
| Fix advice | Not listed on its pricing page | The exact DNS record to add or change, for your DNS host |
| Inbox placement tests (seed accounts) | Yes, 300–1,500 per month on paid plans | No. A single-email test reads authentication and content |
| Contact verification | Yes | No |
| Hosted redirects and masking proxies | Yes | No. EmailHealth only watches that a domain's redirect still works |
| DMARC reports | Yes | Yes, free DMARC report inbox |
| Free plan | 1 domain | 1 domain monitored daily; free one-time checks with no account |
| Paid plans | $49/mo for 25 domains, $129/mo for 75, $199/mo for 200 | Early access: 10 domains free while pricing is set |
EmailGuard figures are from its public pricing page in October 2026 and can change.
What EmailHealth checks on each domain
- MX records and the mailbox provider behind them
- SPF: one record only, under the 10-lookup limit, with the policy at the end
- DKIM keys at common selectors, and key size
- DMARC policy, pct and report address
- Domain blocklists and the sending IPs found in DNS
- TLS certificate, MTA-STS and TLS-RPT
- Changes to name servers and records, and domain expiry dates
When something changes, you get one message that names the domain, what changed, and the record that fixes it. A weekly digest lists every domain that still needs work.
Try it on your domains
Run the cold email domain health check on up to 5 sending domains with no account. To watch a whole list every day, add the domains to an account: 1 domain is free, and early access covers 10.
