Maildoso manages your DNS
To get the best deliverability with our sending infrastructure, Maildoso fully manages DNS for the domains you use with us. You connect a domain by pointing it to our two nameservers at your registrar, and we handle the MX, SPF, DKIM and DMARC records automatically. Because of this, a few things work differently than on a domain you manage yourself:
Custom nameservers and manual DNS records
At your registrar you must set only our two nameservers — nothing else. Extra or leftover nameservers, or expired ones, will stop DNS from resolving and mailboxes will fail. If a domain gets stuck pointing its nameservers to us, see My domain shows "NS Not Set" — what does this mean?
You can't add or edit DNS records (MX, CNAME, TXT, etc.) by hand — they're managed for you. If you need a specific record, contact support and we'll review it.
You can verify the records we publish with an external tool such as easydmarc.com/tools/dmarc-lookup or MXToolbox.
Custom open/click tracking domains aren't supported
Sequencers like Lemlist and Smartlead use a custom tracking domain (a CNAME record) for open and click tracking. Since we don't allow third-party CNAME/TXT records on managed domains, that tracking domain can't be verified, so the sequencer's open/click tracking won't validate on a Maildoso-managed domain. Sending itself is unaffected. Maildoso instead applies tracking automatically through Global Custom Domain Tracking — see Where can I find custom domain tracking for my tool? for where that setting lives.
DMARC reporting
DMARC is configured and managed by Maildoso for best deliverability. Custom DMARC policies or custom reporting addresses (rua) aren't something you set yourself on managed domains, and this isn't on the roadmap.
If you were planning to use DMARC aggregate reports or Google Postmaster Tools verification for your own independent monitoring, those wouldn't add useful visibility for a Maildoso setup anyway — the signal that matters here is mailbox reputation, and you have two direct views of it:
The reputation we measure and show for each mailbox inside your Maildoso account — see Understanding your mailbox reputation scores (Google Score & Microsoft Score) and Understanding your Warmup & Deliverability Insights.
Mailbox reputation and placement inside your warmup tool.
Those two are the most important things to watch. Sending IPs aren't something you need to monitor — we track their reputation and blacklisting status and rotate them on our side; see Can I get a dedicated sending IP for my mailboxes?
Cloudflare-registrar domains
Domains registered through Cloudflare Registrar are locked to Cloudflare's own nameservers and can't be repointed to ours. These domains can't be used with Maildoso unless you transfer them to a registrar that allows nameserver changes. (This is different from a domain that merely uses Cloudflare for DNS.) See Using domains registered with Cloudflare Registrar for your options.
