Tips to avoid spam filters
Always include an unsubscribe link
Not only is it legally required in most countries, but missing unsubscribe links are a major spam signal. Pigeon adds one automatically to every campaign.
Balance images and text
Image-heavy emails with little text are a classic spam pattern. Aim for at least 60% text content in your emails.
Authenticate your domain
SPF, DKIM, and DMARC are the most important technical factors for inbox delivery.
