Welcome to the SenderWorx Blog
Email deliverability is one of those things that feels invisible until it breaks. One day your open rates drop, or a client calls to say their transactional receipts are landing in spam. Suddenly you are scrambling to understand authentication records, blocklists, and reputation scores that nobody told you existed.
That is exactly the problem the SenderWorx blog is here to solve.
What we will cover
We write for the people who actually send email: growth teams, developers, deliverability managers, and anyone who has ever stared at a bounce report wondering what went wrong. Expect posts on:
- How email authentication (Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting and Conformance (DMARC)) actually works, in plain English
- Reading and acting on feedback loop data and bounce categories
- List hygiene: why cleaning your list protects your reputation and your budget
- Blocklist basics: what puts you on one, and how to get off
A quick example: checking your sending domain
Before any of the advanced topics, here is a one-liner you can run right now to see your domain's SPF record:
dig TXT yourdomain.com | grep spfIf the output is empty, you do not have an SPF record, which means receiving mail servers have no way to verify that your sending IP is authorized. That is a common first step toward deliverability problems.
