    What DNS records are compulsory to create so that I can use Maileroo?

    To use Maileroo with your domain, add an SPF record authorizing its servers and publish the DKIM public key generated in Maileroo. These compulsory DNS records authenticate outgoing email and support delivery. A DMARC record is optional but can further strengthen email security.

    I already have MX records. What do I do?

    Already have MX records? No changes are needed. Maileroo operates independently of your existing mail exchange setup, so you can keep using your current mail servers while sending transactional emails through Maileroo. Delivery works without additional MX configuration or disruption.

    I already have a DMARC record. What do I do?

    Already have a DMARC record? You don’t need to change it to use Maileroo. Your existing policy will continue to protect email sent from your domain, including messages sent through Maileroo. Keep the record as configured, and contact support if you need assistance.

    I already have an SPF record. What do I do?

    Add Maileroo to an existing SPF record by inserting include:_spf.maileroo.com in your domain’s DNS settings. Save the update, allow up to 48 hours for propagation, then validate the record and rescan it in Maileroo. Check syntax and stay within the 10 DNS lookup limit.

    How long does it take for DNS changes to propagate?

    DNS changes usually propagate across the global network within a few minutes to 48 hours, depending on several factors. After setting up Maileroo records, wait at least 10 minutes, then use an external DNS lookup tool such as NSLookup to check whether updates appear on other sites.

    Why is my DKIM key exceeding the character limit?

    Long DKIM keys, especially 2048-bit keys, can exceed a DNS provider’s 255-character TXT string limit and break email authentication. Check the provider’s limit, split the record into properly quoted strings, update DNS, and test it; receiving mail services will merge the parts.
