Email sequencing without deliverability guesswork.

About us

Every cold email tool promises deliverability. Most share infrastructure across thousands of users so when one account burns, everyone suffers. Sendkit is different. We built isolated infrastructure from the ground up. Dedicated IPs. Warmup that mimics real human behavior. Auto-protection that pulls failing mailboxes before damage spreads and brings them back when they recover. The result? 95%+ inbox rates for teams who refuse to settle for promotions or spam folders. Built for teams scaling outreach, agencies managing client campaigns, GTM teams scaling outbound, and any business ready to take their cold outreach to the next level.

    Just wrapped up an outbound campaign and the numbers are worth sharing: 1.3k leads, 66.9% contacted 2.9k emails sent 6.33% reply rate 60% positive sentiment (34 positive replies) 1% bounce rate 6 deals signed The stack behind it: Porkbun for domains, cheap and reliable for spinning up sending infrastructure Inboxkit for mailboxes, fast setup and clean IP reputation out of the gate SendKit for sending, handled volume without deliverability headaches Clay for enrichment, this is where the campaign actually won Infrastructure gets the email delivered. Copy gets it read. I wrote every sequence to sound like a person noticed something specific about the prospect's business, not a template with merge tags. Combined with Clay's firmographic and intent data, that personalization is what pushed positive sentiment to 60%. Timing mattered too. Follow-ups sequenced around real buying signals, not just day 3, day 7 defaults, added 10 extra replies on top of the initial send. But the number that actually matters: 6 signed deals from this campaign. Reply rates and positive sentiment are nice, but pipeline that closes is the only metric a client actually cares about. Good infrastructure gets you delivered. Good data and good copy get you replied to. Good follow-through gets you paid. Happy to talk through the setup if you're building something similar.

    Day 109 of building Legacy GTM to a million dollar agency. 🚀 It's 2:48 AM on a Sunday and I just set the most audacious 107-day goals of my life. And I'll be documenting it all on LinkedIn. Announcing it here first. 👇 By October 13th, my birthday: 💰 Legacy GTM will be at $50k/month 📈 My profile Harvey Le will be at 10k followers 🏃 I will finish a marathon (race day is October 5th) Why am I confident this will happen? Here's what I've got dialed in: ⸻ 1️⃣ The outbound motion at Legacy GTM is ramping up. Me and Iyiolaoluwa Neil Uko are launching new campaigns every day, both on SendKit for emails and HeyReach for DMs. And I'm going crazy on good Upwork job posts. (2 of my current clients, and my biggest one, came from Upwork.) 🔥 ⸻ 2️⃣ I'm partnering with AJ Cassata. My first cold email mentor, the one who taught me how to send my first cold email back in 2021. 🙏 Together we're releasing one of, if not THE best cold email webinar on the planet. We're making this a full funnel strategy, with insane content and ads in play. Everything's been planned and shot, and now we're onto post production. 📅We're launching in the end of July, and LinkedIn will not be ready for what we're about to drop. 30 days of content pre launch, and 30 days of content post launch. Insane value. Hollywood level post production quality. This will generate followers for both of us, drum up hype for the launch, and bring in client enquiries. So make sure you follow me and AJ Cassata so you don't miss it 😉 ----- 3️⃣ I just reinvested all of my agency profits into an agency coaching mentorship program. The same one that helped some of the best agencies I know scale from 0 to 100k within a year. This sprint will level me up as an entrepreneur, to sell better, hire better, and build better systems, so my clients get the best results. 💪 ------ 4️⃣ I've recently prioritized my health a lot more. I'm starting to feel the effects of my 9PM to 5AM schedule the last 2 years. So now it's non-negotiable: Running every day Long runs on the weekends (10km+) Gym twice a week and eating healthier. Last year my marathon attempt got cut off at 24km, 4 hours in. 🎯 This year I will cross the finish line within 6hrs. Even if I have to crawl. - I've said many times in my life that this year will be different. Well, this year WILL be different. Because I will make it different. Personally, I know I'm about to pop the fudge off. So LinkedIn… be ready for this heat. 🔥

    I cut my client reporting time by about 90% this month. Not from hiring help or building a fancy system. From a single tool finally doing what it promised. Client reporting used to be a nightmare. Pull stats from the sequencer. Push to Airtable or Google Sheets. Export a PDF. Format everything in Canva or Gamma. Send it manually. And it broke roughly every other week. That whole process was eating hours I didn't have. Now it's 2 clicks with SendKit. Literally 2 clicks and the report is done. Here's why this matters more than people realize: When you're running outbound for multiple clients, reporting isn't just admin work. It's trust-building. Clients want to see what's happening with their campaigns. They want clean numbers, fast. If your reporting looks messy or takes forever, it signals that your whole operation might be messy. So when a tool removes that friction entirely, it doesn't just save you time. It makes you look sharper to your clients. That's the part most people sleep on. So what do you use for client reporting?

    Nobody talks about the thing that actually kills your campaigns before they even start: Email deliverability. I use SendKit for my go to email automation tool. And they built two features that solve this: - Detect if an email is protected by a Secure Email Gateway - Identify if the lead uses Gmail, Outlook, Yahoo, or another provider Why does this matter? Because now I can match my sending mailboxes to recipient email providers. Gmail leads get emails from Gmail accounts. Outlook leads get Outlook. And for those enterprise leads hiding behind Proofpoint or Mimecast? I decide how to handle them separately because those security gateways destroy cold email campaigns. Most people are sending blind. I'm sending smart. That's the difference between inbox and spam, and honestly, between wasted time and actual replies. You can't fix deliverability with only better copy. You fix it by controlling who sends to who.

    🔧 30 days on SendKit. Replaced 4 tools and a reporting chain. Full breakdown: Most cold email stacks are undiscovered debt. You don't see it until something breaks mid-campaign. Here's what left my stack over the past month: -Plusvibe (sequencer) -Airtable (reporting and tracking) -n8n (Slack alerts, deliverability monitoring) -Canva (client PDF reports) -A tedious reporting chain What I run now: Just SendKit. One thing that stuck with me: I mentioned a mailbox management UX issue to their team. They fixed it and added me to their contributors page. I didn't expect either of those things. In a category where most feedback disappears into a backlog, that's incredible. Deliverability is excellent. Dedicated infrastructure, no shared queues. The sequencer is clean and does what it needs to. But the real change was simpler. Client reporting used to be: pull stats from sequencer, push to Airtable, export PDF, format in Canva, send manually. Broke roughly every other week. Now it's like, 2 clicks. If you're running Smartlead/Plusvibe plus a support stack of other tools, it's definitely worth a look.

    You can launch an outbound campaign faster than you think. I’m not saying you’ll be successful. I’m just saying you can get the campaign started. 1. Email infrastructure: Maildoso and Inboxkit 2. Lead list: A-Leads Why? Real-time verification means fresh data. And A-Leads won't charge you for leads they can't verify. 3. Personalization and Orchestration: Claude Code 4. Email automation: SendKit Those who know me know that... I use far more GTM tools in my agency than I share here. Probably more than 15. But here’s the only thing I want to say: Don’t overcomplicate it. This is where the testing process for outbound begins. If you’re looking for a cost-effective roadmap to get started quickly, This can help you get started. P.S. I just can't understand why some people spend a whole week creating an outbound campaign. Because speed is key to finding the best offer.

    If you’ve ever tried to scale outbound pipeline without a large SDR team, you’ve probably done this: -Stack 3-4 enrichment tools. -Pay for the same contact three different ways. -Still end up cleaning junk data manually. At some point it clicks. The stack is the problem. Here’s what actually worked for me: Start with clean data at position one.  Prospeo.io runs a 7-day refresh cycle on its entire database of 300M+ contacts.  That's not just marketing claim, it's what shows up in real bounce rates.  I sent 10k emails without re-verifying the data Prospeo.io gave. 0% bounce rate. So instead of layering tools, I replaced most of them. Put it first in your enrichment waterfall and the foundation for everything downstream gets dramatically more reliable. I use BetterEnrich since it complements Prospeo, but the stack is a lot simpler now. Then protect your sending infrastructure like it's the asset it is. I use my own custom SMTP mostly, but my go-to for Google Workspace accs is theboomerang dot co and slicey dot ai for Azure/MSFT. SendKit (the sequencer) gives each account its own dedicated IP and isolated sending environment.  No shared queues or shared reputation. When a mailbox underperforms, it’s paused and recovers on autopilot. Then add the personalization logic. Clay (I've now fully replaced this with BetterEnrich for orchestration) pulls enrichment context, AI writes first lines from that context. Enriched records push to SendKit. Contacts without emails are sent into a La Growth Machine campaign (if they have LinkedIn URLs ofc). LGM's lookalike finder and AI copywriting assistant make finding new contacts and writing messages so much easier its criminal. The whole research-to-send flow now runs seamlessly with little no no manual cleaning/enrichment. But the biggest change wasn’t the tools. It was removing the ones I didn’t need anymore. You don't need more headcount.  You need cleaner data, better infrastructure, and tighter ICP logic working together.
