TL;DR
Upgrades are done from the Billing page, click your initials at the bottom left of your dashboard and select Billing
Scroll down to Your Sending Bundles and click Add Another Bundle
Each bundle adds 1,000 emails per day, stack as many as you need
You can choose between Monthly, 6 Month (save 10%), or Annual (save 15%) billing
Once payment is confirmed your new bundle is active for setup right away. Existing inboxes keep sending.
Branded new inboxes need about 2–3 weeks of warmup plus about a 7-day ramp. Pre-warmed inboxes have no warmup, can send ASAP, and still have about a 7-day ramp.
Why this matters / When you'd use this
As your campaigns get results and you want to reach more people, upgrading your sending volume is the natural next step. Adding bundles is how you scale — each additional bundle adds another 1,000 emails per day to your daily capacity, along with its own set of credits, domains, and inboxes.
How to upgrade
Step 1 - Go to your Billing page
Click your initials at the bottom left of the sidebar. A menu will appear, select Billing.
Step 2 - Click Add Another Bundle
Once inside the Billing page, scroll down to the Your Sending Bundles section. You will see your current active bundle listed here. Below it, click the Add Another Bundle button.
Step 3 - Select your sending volume and billing plan
You will be taken to the plans page. You can also open it directly from Plans in the same profile menu. Here you can:
Use the Sending Bundles selector to choose how many bundles you want to add, each bundle adds 1,000 emails per day to your daily capacity
Toggle between Monthly, 6 Months (save 10%), or Annual (save 15%) billing
As you adjust the number of bundles, the page updates in real time to show you exactly what is included, credits per month, sends per month, domains, inboxes, and daily sending capacity, and your total cost.
Step 4 - Confirm and complete payment
Once you have selected your volume and billing preference, click Start with Monthly Plan (or whichever billing option you selected). You will be redirected to complete payment. Once payment is confirmed, your new bundle is active.
What each additional bundle includes
Every bundle you add comes with its own full set of everything:
10,000 triple-verified lead credits per month
Up to 80,000 Email Engine sends per billing period, shown on the Campaign page. That is more than the bundle's own inboxes send (about 1,000 a day), so you can connect your own inboxes and send more. If scheduled sends go over the allowance, they continue next period. Sending is not blocked.
20,000 stored contacts. Only contacts in Active campaigns count (drafts don't), and deleting a campaign frees space.
20 .com domains and 40 Google inboxes, registered, configured, warmed up, and managed for you
What happens after upgrading
Once your new bundle is active, you will need to set up its domains and inboxes before it can send. Head to your Billing page, scroll down to the Bundle Setup section, and click Setup Now next to your new bundle. The setup process is exactly the same as your first bundle.
For a full walkthrough see: What are ListKit's pre-warmed inboxes and how do I set them up? (or How do I set up new branded domains and inboxes for my Bundle? for new branded domains)
Pre-warmed inboxes (recommended) can start sending within minutes and ramp up to full volume over 7 days. New branded domains need 14 days of warmup, plus up to 72 hours to register domains and start warmup (about 2 to 3 weeks from signup).
Billing plan options
Monthly
Pay month to month. Cancel any bundle independently at any time.
6 Months - Save 10%
Commit for 6 months and save 10% on the total cost.
Annual - Save 15%
Commit for 12 months and save 15% on the total cost. Best value for customers who are scaling consistently.
A note on domains and renewal
Domains are included free for as long as you stay subscribed. ListKit renews them for you and there is nothing extra to pay.
Expected outcome
After completing your upgrade and setting up your new bundle's domains and inboxes, your daily sending capacity increases by 1,000 emails per day per bundle added. Once the new inboxes show as Ready on the Inboxes page, add them to your campaigns alongside your existing infrastructure.
Troubleshooting / FAQs
Can I upgrade mid-month?
Yes. You can add a new bundle at any time. Each bundle is billed separately from its own signup date (the day you add it) and renews on that date. ListKit does not prorate, so the new bundle is charged in full on the day you add it, and your existing bundles keep their own dates.
Do I need to go through the demo call again to upgrade?
No. Once you are a ListKit customer, you can upgrade directly from inside the app through the Billing page.
Can I cancel individual bundles independently?
Yes. Each bundle renews on its own date and can be cancelled independently without affecting your other active bundles.
Do my new inboxes need to warm up?
Not if you choose pre-warmed inboxes. They only need the 7-day ramp-up. New branded domains need 14 days of warmup, plus up to 72 hours to register domains and start warmup (about 2 to 3 weeks from signup). Your existing inboxes are not affected and continue sending while new ones warm up.
Do my domains expire while I'm subscribed?
No. Domains are free for as long as you are subscribed, and ListKit renews them at no charge. You keep the same domains and don't need to set up or warm up new ones.
I completed payment but my new bundle is not showing up.
