In this article, you will learn how to make the DNS configuration needed for good deliverability and to meet the authentication requirements of email providers.
We will split this into two steps: first you configure the record on your edrone platform, and then you add that record on Registro.br.
Step 1 - Configuring your DNS records in edrone
Go to your edrone dashboard and open SETTINGS > SENDING DOMAIN.
If you have not added your domain yet, click Add domain.
Click Configure DNS records, then Go to DNS configuration.
By default, edrone will show you the recommended NS records to configure your sending subdomain. Copy the values straight from your edrone dashboard - they are unique to your account - and paste them exactly, with no extra spaces.
Registro.br's Advanced Mode does not accept NS records for subdomains. If you are on Registro.br, click I can't configure NS records inside the edrone DNS configuration dialog. edrone will switch you to an alternative set of standard records (CNAME and TXT) that Registro.br does accept.
⚠️ Important: with the previous process you had to add SPF, DKIM, and DMARC entries one by one. Now you only need the records edrone shows you after switching to the alternative configuration.
Step 2 - Adding the records on Registro.br
Sign in at registro.br: click ACESSAR CONTA at the top right, enter your code, CPF/CNPJ or domain plus your password, then click AVANÇAR.
In Meus domínios, click your domain name to open its admin screen.
In the DNS section, click Configurar Zona DNS.
Choose Modo Avançado (Advanced Mode). It allows up to 40 records: A, AAAA, CNAME, MX, TXT, and TLSA. The transition can take about 5 minutes - refresh the page until the New entry button appears.
Click New entry, pick the record Type, and fill in the Name (host) and Value exactly as shown in your edrone dashboard. Keep the TTL at 3600, then click ADD.
Repeat this for every record edrone shows you, then click SAVE CHANGES.
Go back to the edrone dashboard and click Verify records to validate the configuration.
📌 Tip: for MX records, root-domain TXT records, and root A records, leave the Name field blank or use "@". This usually does not apply to the subdomain records edrone asks for, but it is useful to know if you manage other records in the same zone.
Keep in mind that propagation can take from a few minutes up to 72 hours.
Alternative: delegate DNS to another provider
If you would rather manage your DNS somewhere else (for example Cloudflare or AWS Route 53), you can delegate your domain's DNS to that provider. This lets you use the simpler NS-record method there instead.
Sign in at registro.br and select your domain, as described in Step 2.
Click Alterar servidores DNS (Change DNS servers).
Fill in Server 1 and Server 2 with the nameservers of your new provider (for example, ana.ns.cloudflare.com).
Click Save.
⚠️ Important: once you change the nameservers, Registro.br's own DNS zone stops applying - you will need to add all your DNS records with the new provider. Propagation can take up to 72 hours, so keep the old nameservers active during the transition.
If you choose Cloudflare, see our article How to configure DNS on Cloudflare.
What if my DNS provider does not support NS records
This is the most common scenario on Registro.br, since its Advanced Mode does not accept NS records for subdomains. Click I can't configure NS records inside the edrone DNS configuration dialog to switch to the alternative CNAME/TXT records described in Step 2. If Registro.br ever supports NS records for subdomains, you can switch back by clicking Use recommended records.
You can find the full walkthrough in the article How to verify your domain if your provider does not support NS records?
Verifying your records
In edrone, click Verify records. The status turns green once your DNS changes propagate - this can take from a few minutes up to 72 hours.
On Registro.br, you can also check your records under Tecnologia > Ferramentas > Verificação de DNS (Technology > Tools > DNS Verification).
You can also check propagation externally with tools like dnschecker.org, mxtoolbox.com, or whatsmydns.net.
