About this gig
Is your Sendy API failing, webhook not firing, SMTP not sending, or emails landing in spam?
I will troubleshoot and fix Sendy technical issues affecting API connections, webhooks, SMTP delivery, bounce/complaint handling and email deliverability.
I will identify the likely root cause, apply the required fixes, test the sending flow and explain what was changed.
I can help with:
- Sendy API errors, invalid API key, list ID and subscriber sync issues
- Webhook setup, testing and failed event callbacks
- SMTP connection, authentication and sending errors
- Amazon SES/SNS connection and bounce/complaint handling
- SPF, DKIM, DMARC and DNS-related delivery issues
- Sendy sending, tracking, cron and server configuration problems
- Spam, bounce and failed delivery diagnosis
Message me before ordering with your Sendy URL/version, error message or screenshot, sending provider, and the exact problem.
