Improve email deliverability
Fileflare has the best email deliverability you can get. As default, download emails are delivered from noreply@digital-downloads.com. Our systems have all the things in place which maintains the highest deliverability, such as DKIM, SPF, DMARC, plus a high reputation for sending millions of emails every month.
Please learn about DMARC, DKIM, and SPF. You need to be very careful following the below steps because if you mess something up in your DNS settings, your domain could stop working. I would recommend getting a professional to do this or someone who is technical.
DomainKeys Identified Mail (DKIM) is an authentication method that uses asymmetric encryption to sign and verify your email. With DKIM implemented, the sending email server adds a cryptographic signature to your emails' headers. The DKIM record is a TXT record that stores the DKIM public key. For more information about how DKIM works, see DKIM Records Explained .
Sender Policy Framework (SPF) is an email authentication standard developed by AOL that allows you to list all the IP addresses that are authorized to send email on behalf of your domain. The SPF record is a TXT record that lists the IP addresses approved by the domain owner. The receiving server can compare the email sender’s actual IP address to the list in the SPF record. For more information about how SPF works, see SPF Records Explained .
Domain-based Message Authentication, Reporting & Conformance (DMARC) is a protocol that verifies the authenticity of an email's sender. It helps prevent malicious senders from harming your sender reputation. DMARC provides a policy to email service providers, instructing them on the actions to take when they receive an email that fails SPF, DKIM, or both checks, and appears to be from your domain—a sign it may be spoofed.
DMARC is an optional field for Sender Authentication. SendGrid suggests starting with the simplest DMARC policy: v=DMARC1; p=none . However, your organization may enforce a stricter policy, which you should then apply. Twilio SendGrid will accept any valid DMARC policy during its verification process. For more information on DMARC, please refer to the article, Everything about DMARC .
Once you have the below set up on your domain, you will be able to get the best deliverability rates.
The DMARC will be set up using this app and your DNS settings. It's best this way because it creates and handles your DMARC for you, and it also reads the reports and puts them in a graph so you can understand who is trying to spoof your domain.

The DKIM will be set up in SendGrid, and your DNS settings.
Log into your SendGrid account
Go to Settings
Go to Sender Authentication
Click the "Authenticate Your Domain" button
Follow the steps to complete the setup and verify the adjustment
If you use Google for your email, then you can set up DKIM with your domain using the below.
Log into your Workspace Admin Console
Go to Apps > Google Workspace > Gmail.
Go to the "Authenticate email" box
Create your DKIM and add it to your DNS

This will show you how to add an SPF to the DNS.
Log into your domain DNS provider and go to the DNS settings
Here, you will enter a TXT record for your SPF. Please copy the one below if you are only using Google and SendGrid. If you are using other email delivery apps, you will need to include them, too.
The SPF is what you will inform which platforms are allowed to send email using your domain. For this example, we are only using SendGrid and Google Workspace, so your SPF will look like this:
v=spf1 include:_spf.google.com include:sendgrid.net ~all

It's a must that you should set up Reverse DNS is your email address is sending over 5000 daily. Ensure that sending domains or IPs have valid forward and reverse DNS records, also referred to as PTR records. Learn more .
In SendGrid
You can easily set this up in the Sender authentication section in SendGrid. Learn more .
Keep spam rates reported in Postmaster Tools below 0.30%. Learn more about spam rates .
It's OK if you go above this for brief periods (the odd day here and there). If you continue to stay above, your emails will fall in the spam folder regularly.
