Your emails keep landing in spam, and it’s not your subject lines. Sender Score reveals the reputation of the infrastructure sending your mail. This guide explains what it measures, how to check it for free, and the specific steps to improve it.
You’ve heard Postmark has a reputation for getting transactional email to the inbox, but the pricing page and feature list never tell you whether it’s right for your site.
Will it actually fix your deliverability, and does it play nicely with WordPress? We ran test sends through Postmark on three WordPress sites to find out.
Here’s the honest review: its real pricing tiers, deliverability record, the features that matter, the pros and cons, and exactly how to connect it with WP Mail SMTP.
A hard bounce is permanent and a soft bounce is temporary, but the real problem is that WordPress can’t see either one. Here’s how to tell them apart, read the SMTP error codes, and find and fix both types of bounce on your site.
Your emails say they’re sending. The logs look clean, the success message pops up, and everything seems fine. Then a customer asks why they never got their password reset, and you realize your mail has been quietly landing in spam for weeks.
Testing your deliverability turns that guesswork into a clear score you can act on.
Here’s the full process, step by step. Run a spam score test, check your SPF, DKIM, and DMARC records, send a real test from WordPress, and read an inbox placement report.
Use your favorite SMTP provider to reliably send your WordPress emails.
SMTP, IMAP, and POP3 are easy to confuse, but the distinction is simple: SMTP sends your email, while IMAP and POP3 receive it. Learn how all three protocols work, which ports they use, and what it means for the emails your website sends.
