Prevent deliverability issues, such as being caught in spam filters, prior to sending marketing emails.
You can find the DKIM and SPF records by checking your email service provider such as G Suite, Microsoft, GoDaddy etc.
Check whether the platform you are planning to use for marketing emails requires you to add any extra records to your DNS.
Optionally, you can add a DMARC record to your DNS for extra protection.
For newly created email addresses - less than a week old - manually send a few emails every day for a couple of weeks.
Email providers flag brand-new email addresses-send and receive regular emails with the new email account for at least a month.
Send these emails from the account inbox without any automation involved - as you would to a friend or colleague. Make sure to send emails to a variety of email address types like personal Gmail accounts and business accounts.
In your marketing email templates, include a clear unsubscribe link and a description of why the recipient is receiving the email.
For example, “You’re receiving this email because you signed up on [website].”
There are anti-spam laws in some countries that require a physical address to be included in emails. Therefore, it’s a good practice to add them for your email templates.
