curl -X POST https://pubsub.googleapis.com/v1/projects/[projectname]/topics/[topicname]:publish
     -H "Content-Type: application/json"
     -H "Authorization: key=[mykey]"
     -d '{"name": "name", "email": "email"}'

Please try to put your data inside the messages tag.

For your case, please try

curl -X POST \
  https://pubsub.googleapis.com/v1/projects/[projectname]/topics/[topicname]:publish \
  -H 'Accept: */*' \
  -H 'Accept-Encoding: gzip, deflate' \
  -H 'Authorization: Bearer <<generated access token>>' 
  -H 'Content-Type: application/json' \
  -H 'Host: pubsub.googleapis.com' \
  -d '{
  "messages": [
    {
      "name": "name", "email": "email"
    }
  ]
}'
