Email Client Testing
Use Inbox Inspector to make sure your email design looks great in all the major email clients. There are approximately a trillion different clients out there, so we do the work for you by automatically selecting the 10 most‑used clients in your subscriber list.If you’d prefer to pick which clients will be included in the inspection, you can do that, too. If you want to see more than 10, you can run as many inspections as you’d like. Users with monthly plans get up to 25 free inspections per week.
Spam Filter Analysis
Inbox Inspector helps you stay out trouble by looking for words and phrases that trigger spam filters, then it tells you specifically what’s so spammy about your email. Trust us—it’s better to find out ahead of time if your message looks like spam.
Mobile Previews
Before you send a campaign, make sure it’s going to look great on screens big and small. We’ll test the email in your subscribers’ most-used apps, or you can choose the mobile email apps you’d like to test.
