Question 1

What Twitter card type does resend.com use?

Accepted Answer

resend.com uses the `summary_large_image` card type. This renders a large hero image above the title and description - the most engaging format.

Question 2

Does resend.com declare image dimensions?

Accepted Answer

resend.com sets `og:image` but does not include `og:image:width` and `og:image:height`. Explicit dimensions let platforms render the preview faster without downloading the image first.

Question 3

What headline does resend.com use for social previews?

Accepted Answer

resend.com's social headline is "Resend · Email for developers" (29 characters).

Question 4

What description does resend.com use for social previews?

Accepted Answer

resend.com's social description reads: "The best way to reach humans instead of spam folders. Deliver transactional and marketing emails at scale." (106 characters).

Question 5

What's the biggest issue with resend.com's Twitter / X preview?

Accepted Answer

Missing og:type tag. Platforms default to "website" but explicitly setting it ensures correct rendering.

Question 6

How can I improve resend.com's social previews?

Accepted Answer

Review the recommendations above - they list specific issues and provide ready-to-paste meta tag snippets. The highest-impact fixes are usually a properly sized `og:image` (1200×675), a clear `og:title` under 60 characters, and a 50-155 character `og:description`.
