Something most people don't think about: setting up mailboxes should take seconds, not hours. That's exactly why I started paying attention to tools like Inboxkit. Under 10 seconds. That's all it takes.

I don't recommend inbox providers unless I have used them myself. Deliverability is too important to guess on. Today we officially became a Platinum Partner.

If you're serious about email deliverability your results are only as good as your infrastructure. Inboxkit gives you everything you need to land in primary: US-IP Google Workspace & Microsoft 365 mailboxes, automated DNS, SPF, DKIM & DMARC setup, built-in warmup, blacklist monitoring & inbox placement tests. Ready in under 10 minutes. Zero manual work.

I've been using InboxKit for quite some time now across multiple outbound setups, and honestly, zero deliverability issues so far. Stable infra, clean inboxes, and predictable performance, which is rare in this space.

I still get asked how to set up simple, effective cold email. I recommend the same 3 tools every time: InboxKit – Email infrastructure. Prospeo.io – The best verified email + phone provider. Instantly.ai – Easy sending that integrates with your stack. Keep it simple. Get your V1 live. Then iterate.

I don't usually talk about tools. But I've been dealing with the same email infrastructure frustrations for months. I got tired of guessing. That's why I've been using InboxKit. Their dashboard shows real-time deliverability and sender reputation by domain. I can see problems forming before emails hit spam.

Your cold email infrastructure provider isn't a vendor at scale. It's load-bearing. We run 100+ active client campaigns on Inboxkit — thousands of domains, millions of sends a month.

95% deliverability guarantee. Let me say that again: NINETY-FIVE percent. I've never seen an inbox provider put that in writing before. Setup time? 15 minutes vs. the 2+ hours I've spent with other providers.

Dear edu and legacy resellers, thanks for reminding me why diversifying and having backup inboxes is so important. Good thing we weren't impacted. Huge shoutout to our trusted partners for that: InboxKit + ScaledMail for Google. Lesson: choose your inbox provider wisely.

I'm proud to say Scaletopia is now an official InboxKit Platinum Partner! We've been running on them for the last 8 months after testing a bunch of other providers, and these guys have just been the most consistent and the most stress-free of the lot. The infrastructure holds up, inbox placement over 95%, and I stopped having to think about deliverability altogether.

Never shared campaign metrics here - but thought this is worth sharing, specially cause I wanted to give props to my dudes at SendKit and Inboxkit. This campaign was created in less than 10 minutes. This is less than 8 hours of sending - First touch. Not too bad eh?

I've sent millions of emails and managed thousands of inboxes. The gap between teams sending 10K emails/month and 500K emails/month isn't better copywriters. It's better infrastructure. InboxKit has been my solution for the past 6 months - managing 100+ mailboxes with a unified dashboard, automated health monitoring, and real-time deliverability tracking.

Breaking: Google just wiped out thousands of “cheap” email accounts. If you are relying on cheap email resellers, you could be next. Want a reliable email infrastructure for your cold email campaigns? Check out Inboxkit. Not only are they official Google Cloud Partners, they give you insanely good email deliverability and offer damn good customer support.

New PB unlocked. 425 positive replies in February. Thats a lead every 89 contacts or every 151 emails. Deliverability is number one: ensuring we are getting at least a 3% reply rate is an indicator we not landing in spam. But if they do drop we'll use the Inboxkit API to spin up new domains and inboxes.

Almost nobody talks about why so many perfect emails never get seen. Most of the time, it's not the message. It's infrastructure. That's why I'm working with InboxKit. I've been using them, and when they asked to partner it was an easy yes.

A client's FIRST campaign launch got 186 leads in 3 days. 70% Positive Reply Rate. Legacy GTM's biggest launch, and my personal record for time to 100 leads. Didn't use Clay, no crazy signals. Just the fundamentals and solid tech stack: inboxes that gets you in the primary by Inboxkit.
