GlockApps checks many inboxes—but not the ones that matter most.
GlockApps covers a wide range of mailbox providers, including country-specific and personal email services.
That’s great for B2C campaigns, but when it comes to B2B outreach, it falls short.
GlockApps misses the mark for serious B2B email campaigns.
MailReach does what GlockApps can’t— unbiased spam testing & email warming.
MailReach tests emails across a strategic selection of inboxes. We focus on the right providers for B2B—Google Workspace and Office 365. This gives you accurate, relevant results that matter for professional email deliverability.
Your score adjusts based on the inboxes you’re targeting—whether it’s Professional, Personal, or All Types. For B2B senders, this means you can focus only on what matters: professional inboxes. Get data that helps you reach your target audience.
We help build your email reputation over time with our email warming service—something GlockApps lacks. This ensures that your emails are trusted by providers, so they land in the inbox instead of the spam folder.
Get a complete view of your email deliverability and sender reputation. We get you a reputation score, DNS record checks, blacklist monitoring, and spam checker results. Plus, you can receive real-time alerts via Slack or webhooks to stay on top of your deliverability metrics!
