## How to choose email deliverability software

1. Diagnose before fixingRun a free deliverability test (Mail-Tester, GlockApps free check) before subscribing to a fix tool. Most deliverability issues are simple: missing SPF/DKIM/DMARC, bad list hygiene, content flagged as spam. Fix the basics before paying for advanced tools.
2. Warmup matters for cold emailCold email at any volume needs warmup. Lemwarm, Mailwarm, and Instantly's warmup features all do similar work. For high-volume cold email, warmup is the difference between landing in inbox vs spam.
3. Plan for sender reputation monitoringOnce you've fixed deliverability, monitor it. GlockApps and Folderly run automated tests against your sender reputation across providers. Catch problems before they tank a campaign.
