Hi @micky008,
It's currently not possible to use a list of FormData like we can use a list of files.
I see this PR two years ago old. But no progress with it.
OpenFeign/feign-form#92
Hope it should be possible in the future.
Or we can implement some workaround ourselves but not in the near future.

The solution is very dirty...

I use unirest

public class MyEmailAttachment  {
byte[] content;
String name;
}

public class MailGunService implements IMailerService {

    private static final Logger logger = Logger.getLogger(MailGunService.class);

    @Override
    public void send(List<User> recipient, List<User> ccU, String subject, String message, List<MyEmailAttachment> attachments, String mailingList) throws Exception {

        List<String> to = Collector.collect(recipient, "email");
        List<String> cc = Collector.collect(ccU, "email");

        HttpResponse<JsonNode> request = null;

        String baseUrl = getKey(Configuration.MAILGUN_BASEURL);
        String domain = getKey(Configuration.MAILGUN_DOMAIN);
        String apiKey = getKey(Configuration.MAILGUN_API_KEY);
        String from = getKey(Configuration.MAILGUN_FROM_SENDER);

        String url = baseUrl + "/v3/" + domain + "/messages";

        MultipartBody body = Unirest.post(url)
                .basicAuth("api", apiKey)
                .field("from", from)
                .field("to", to)
                .field("cc", cc)
                .field("subject", subject)
                .field("html", message);

        for (MyEmailAttachment mya : attachments) {
            body.field("attachment", new ByteArrayInputStream(mya.content), mya.name);
        }
                
        request = body.asJson();

        if (request.getBody().getObject().getString("id") != null) {
             for (User user : recipient) {
                logger.info("Email sent to " + (user != null ? user.getName() : "null") + (ccU != null && !ccU.isEmpty() ? " (cc to " + ccU + ")" : "") + (StringUtils.isNotEmpty(mailingList) ? " from Mailing List " + mailingList : ""));
            }
        }
        
        request.ifFailure(error -> {
            logger.error(error.getStatusText());
            if (error.getParsingError().isPresent()) {
                Exception e = error.getParsingError().get();
                logger.error(e, e);
            }
        });

    }

    private String getKey(String key) {
        return DAO.getConfigurationDao().getConfiguration(key);
    }

}
