Here’s a step-by-step tutorial on how to avoid SendGrid emails to go to spam:

‍

You will need to Authenticate your account to avoid spam.
Log into your SendGrid account and go to Settings in the left panel.
Find and select Sender Authentication.
Click on Get Started under Authenticate Your Domain.
Select from the list of providers Eg."Cloudflare".
Click on Next.
You'll need to add DNS records to verify your domain with SendGrid. First, copy these records. (copy icon)
Next, go to where you bought your domain (like GoDaddy, Namecheap, etc.) and find the DNS settings. It's usually under 'Manage Domain' or 'DNS Management'.
Creating a new CNAME record for each of the first three lines.
Creating a new TXT record for the last line.
Pasting the values exactly as shown there.

📌 Why this matters

When you authenticate your domain, you're essentially telling email providers that SendGrid has permission to send emails on your behalf. This prevents your messages from appearing to come from a suspicious third-party server. Beyond just avoiding spam folders, domain authentication builds sender reputation over time, which means your future campaigns will have better deliverability rates.

Email providers also display authenticated domains more prominently to recipients, increasing trust and open rates. Without this setup, even perfectly legitimate emails can trigger spam filters simply due to technical red flags.
