To help ensure your emails reach your customers' inboxes, you can set up custom DKIM authentication for your domain, and add Marsello to your SPF record.
Internet Service Providers (ISPs), like Google, Yahoo, and Microsoft, use DKIM and SPF authentication as a way to scan incoming emails for spam or spoofed addresses. Emails that fail authentication are more likely to arrive in a spam or junk folder.
⚠️ Important: Email providers are now stricter than ever. It is highly recommended to send by a personalized email domain. This will help ensure your emails are delivered to your customers and not being marked as SPAM.

include:sendgrid.netbefore all the mechanisms of this record. If you do not have an SPF record for your domain you must create a TXT record with the value:
v=spf1 include:sendgrid.net ~all
⚠️ Important: Do not create more than one SPF record for a given domain.
If you need more than one SPF record, you will want to merge the additional SPF records into a single SPF record.
If you already have an SPF record for your domain. You would just need to add our lookup at the end of the string, before the

How to create your DMARC Policy:
Open your email domain provider
Navigate to your DNS provider settings
Next to Type select TXT record
In the Name field, enter _dmarc. followed by your complete domain name.
For example: If your domain name is redboutique.com,
Enter: _dmarc.redboutique.com
5. Add the "Value" information
Minimum requirement: To meet the minimum requirement for the DMARC Policy, you'll need to include both v: & p: values.
You can copy and past these recommended values:
v=DMARC1; p=quarantine;
🤔 What do these values mean?
v: indicates the DMARC version.
p: is the policy type that dictates the action for non-passing emails.
Options include:none: Collect feedback and gain visibility into email streams without affecting existing flows.
quarantine: Filter non-passing emails into the recipient's quarantine. (recommended)
reject: Bounce non-passing emails.
Extra for experts: You can also add these values information however the v: & p: values are all you need to meet the minimum requirements.
sp: Apply a policy to a subdomain of the DMARC record.
pct: Percentage of total unique sends that failed authentication to apply the policy to. For instance, if your DMARC record includes p=reject; pct=25, and 100 emails fail authentication, only 25 will be bounced, while the remaining 75 will be delivered to recipients. Defining this property helps gradually implement your authentication policy to ensure it functions as intended. Note that certain inbox service providers may ignore this parameter.
ruf & rua: Optional parameters specifying an email address to send DMARC reporting data to, provided in URI mailto format (e.g., mailto:[email protected]). Reporting data sent varies based on the parameter
rua: Aggregate report of all your domain traffic.
ruf: Failure reporting data, including redacted copies of individual messages that failed authentication.
adkim & aspf: Specifies the alignment mode for DKIM and SPF, both set to r (relaxed alignment) by default. A relaxed alignment is recommended for DMARC in DNS services.
Once you've added and verified the DMARC record with your DNS provider, all receiving email servers can authenticate incoming emails from your domain and handle any failures according to your specified policy.
