Why Is My Email
Going to Spam?
If customers aren’t receiving your emails, check your domain settings, sending services and message content. This guide explains where to start.
The Short Version
Sender Policy Framework must be configured and aligned with your sending servers.
DKIM adds a signature that receiving services can check.
A basic domain validation and reporting policy must be published in your DNS.
Gmail’s Promotions tab
Even if you pass all security checks, Gmail might still hide your email in the Promotions tab if it feels too marketing-focused.

9 Reasons Your Emails Are Going to Spam
Google's Stricter Requirements
Check the sender requirements that apply to your email provider and sending volume. Missing or incorrect authentication can affect delivery.
Bulk-Sender Rules at Low Volumes
Google applies stricter requirements to domains sending 5,000 or more messages a day to personal Gmail accounts. Authentication, easy unsubscribe routes and low spam rates all matter.
Reputation Hit Due to Spam Complaints
Inbox reputation is sensitive. Google recommends keeping spam complaints very low, so even small complaint rates can point to a list, wording or sending-pattern problem.
Misconfigured DNS After Hosting Changes
Moved to Vercel, Cloudflare, or a new host? Duplicate SPF records, long SPF lookup chains, DKIM mismatches, or old DNS records can all make delivery less reliable.
Sending from a New IP or Provider
Switching to a new CRM, marketing tool or notification provider can change the sending IP and domain alignment. Reputation usually needs to build gradually with consistent, wanted messages.
Message content and engagement
Providers use several signals to filter messages. Send relevant, expected emails and review complaints, bounces and unsubscribe requests.
Brand logos and BIMI
BIMI can let supported inboxes display your brand logo. It is optional and does not replace SPF, DKIM or DMARC.
Shared IP Reputation
If you use a bulk mailer on a shared IP pool, one spammy sender can ruin the reputation for everyone, leading to rate-limiting or junk-folder placement for your legit emails.
Alignment Issues with Forwarding
Sending as @yourdomain.com through unaligned services can make messages fail authentication checks. The From domain, SPF domain and DKIM domain need to be planned together.
