Common questions

Is Boomerang for Gmail better than InboxPro for scheduling emails?

Yes, for basic scheduling Boomerang is simpler and works on more browsers. InboxPro can also schedule, but its strength is in sequences, not one-off scheduling.

Can I use InboxPro on my phone?

No. InboxPro is a Chrome extension only — there is no mobile app or mobile browser support. Boomerang also has no mobile app.

Which tool is better for job hunting follow-ups?

InboxPro is better because you can create a sequence of 3-4 follow-up emails spaced days apart, and see if the recruiter opened your message. Boomerang only reminds you to follow up manually.

Do I need to be technical to use Boomerang?

No. You install the extension, grant permissions, and the 'Send Later' button appears right in Gmail. It's very beginner-friendly.

Which tool gives me more AI writing help?

InboxPro's AI Magic Compose can draft full emails from scratch in different tones. Boomerang's Respondable only analyzes your writing for tone and length — it doesn't generate new text.

Boomerang wins for simplicity and price; InboxPro wins for power users who need tracking and sequences.

If you just want to schedule emails, get reminders, and occasionally check your writing tone, start with Boomerang's free plan — it's cheaper and easier. If you're sending lots of follow-ups, tracking opens, or running email sequences (like for sales or job hunting), InboxPro is worth the extra cost despite being Chrome-only.
