What each record does
| Record | What it tells the inbox | If it's missing |
|---|---|---|
| SPF | Which services may send email for your domain | Your emails look like they could come from anyone |
| DKIM | A signature proving the email wasn't changed on the way | Gmail and Outlook trust your mail less, especially at volume |
| DMARC | What to do with email that fails SPF or DKIM | Spoofed emails “from” your domain can reach your customers |
| MX | Where replies to your domain go | Replies bounce, and some filters treat the domain as throwaway |
Checklist before your first cold campaign
- Use a separate sending domain. Keep your main domain for customers and invoices. A lookalike domain (for example get-yourcompany.com) protects it if a campaign goes wrong.
- Set up SPF, DKIM and DMARC with your email provider. Start DMARC at
p=none, move toquarantineonce reports look clean. - Warm up the mailbox. Start at 10–15 emails a day and add a few every couple of days. New mailboxes that send 100 on day one end up in spam.
- Verify your list. Keep bounces under 2–3%. Unverified exports are the fastest way to burn a domain.
- Write fewer, better emails. Replies are the strongest positive signal inboxes see. Personal first lines get more of them than templates.
How LeadScout handles this for you
Campaigns run this same check before every launch, start each new mailbox at 15 emails a day and raise the limit gradually, stop a sequence the moment someone replies, and pause a campaign automatically when bounces go above 5%. Start for free.
FAQ
Is this check free?
Yes, without an account. We only read public DNS records of the domain you enter and don't store it.
Why is DKIM shown as missing when I have it?
DKIM lives under a selector name chosen by your email provider. We check the common ones (Google, Microsoft 365, Zoho, OVH and others). If yours uses a custom selector, check the record in your provider's admin panel.
Is p=none enough for DMARC?
It's the right start: you get reports without risking your own mail. After a couple of weeks of clean reports, move to quarantine, then reject.
Does a perfect check guarantee the inbox?
No. DNS is the entry ticket. Sending volume, list quality, bounces and replies decide where your email lands.
