However, since you now have DMARC

Set up DMARC authentication for your domain
After setting up SPF and DKIM authentication, you’ll need to follow up with DMARC policy.
DMARC authentication tells mailbox providers what to do with an email that fails SPF and DKIM checks, but claims to be from your domain (which could be a case of spoofing, or someone pretending to send mail from your domain).
Your DMARC policy (p) instructions can tell receiving inboxes what to do in this scenario.
None: Receiving inbox does nothing
Quarantine: Receiving inbox puts the message in the spam folder
Reject: Your message is not delivered and produces a soft bounce
What do to: Your domain must have a DMARC record.
The simplest DMARC record you can use list of kuwait cell phone numbers is "v=DMARC1; p=none”, but it's not the most secure.
These instructions tell Gmail that if your emails fail the SPF and DKIM identity checks, they will still be sent to the recipient’s inbox.
This also means that if someone fakes your email address, for example, and tries to send malicious messages, these messages will still go through to the recipient’s inbox.
records, you can track who sent the emails from your domain.
If someone fakes your identity, fails SPF and DKIM checks, and tries to send spam, setting your DMARC policy to “p=reject” will stop those emails from being delivered.

You’ll need to set this up. Learn more about DMARC authentication from our Help Center to get you started.
If you have a p=none policy on your DMARC record, you also need a rua tag on your DMARC to allow receiving DMARC reports.
3. Make sure your sending domain or IPs have valid reverse DNS records
Also known as PTR records, reverse DNS (rDNS) records confirm that your domain is associated with your IP address. When you send emails, the receiving inbox provider (Yahoo!/Google) looks at this record to verify that the IP address sending the email matches the domain.
What to do: If you’re using Brevo’s shared IP address, nothing. This is already done and you don’t need to worry.
If you set up a dedicated IP address with Brevo, you’ve already done this as part of the setup.

4. Keep spam rates below 0.3% according to Postmaster Tools
Any time someone marks one of your emails as spam, your spam rate increases. If your spam rate is too high, your emails will more likely be marked as spam and will not make it to the inbox.
