Install Boostmail and connect your store
Reviewed by Eran Betzalel, founder · 2026-09-30
Installing Boostmail takes a few steps: add the app from the Shopify App Store, approve the standard permissions, and your store is connected, no developer and no code required. Because Boostmail is built specifically for Shopify, it reads your products, customers, and orders directly, so segments and triggered campaigns work the moment the first sync completes. The Free plan is active immediately, with 20,000 free emails every 30 days and no credit card.
Before you start
You only need one thing: admin access to the Shopify store you want to connect. If your store has multiple staff accounts, make sure yours has permission to install apps. You do not need to prepare anything else in advance, your existing Shopify customers and their email marketing consent sync automatically once Boostmail is installed.
What happens on install
When you click Add app, Shopify shows the permissions Boostmail requests. These let the app read customer, product, and order data so it can build accurate segments (for example, “customers who bought in the last 30 days”) and trigger campaigns like abandoned-cart reminders. Boostmail does not change your storefront or theme when you install it.
After you approve, Boostmail opens embedded inside your Shopify admin and begins its initial sync in the background.
Finish setup
Two things make your first send land well:
- Domain authentication, Boostmail requires a verified sender domain. Open Account, go to the Domains tab, enter the address you want to send from, and add the SPF, DKIM, and DMARC records Boostmail gives you. This is the single biggest deliverability lever and is covered step by step in the domain authentication guide.
- Sender name, Each campaign lets you set the sender name and address subscribers will see. A recognizable sender name improves open rates and reduces spam complaints.
Next steps
With the app connected, your Shopify customers are already in place. If you have contacts in a previous tool, bring them over, then send your first message. Continue with importing your subscriber list, then send your first campaign. If you have questions during setup, email support@boostmail.app and the founder will help.

Let the initial sync run
Boostmail imports your existing Shopify customers and their email marketing consent automatically, and keeps consent in sync both ways from then on. The first sync runs in the background; how long it takes depends on the size of your store.

Verify your sender domain
Open Account, go to the Domains tab, and enter the address you want to send from on your own domain. Boostmail requires a verified sender domain, and the domain-authentication guide walks you through the DNS records.
Frequently asked questions
- Does installing Boostmail cost anything?
- No. Installing is free and no credit card is required. The first 20,000 emails every 30 days are free, and Boostmail never charges per contact. Above 20,000 emails you pay per 1,000 emails sent.
- Will installing Boostmail change my storefront or theme?
- No. Boostmail runs inside your Shopify admin and does not modify your live theme on install. Your storefront stays exactly as it is.
- Can I uninstall later?
- Yes. You can remove Boostmail at any time from Settings → Apps in your Shopify admin. Uninstalling removes the app's access to your store.
- My saved link to the app stopped working. Where did it go?
- The app's address inside your Shopify admin changed from .../apps/mailpass to .../apps/boostmail when the app was renamed to Boostmail. A bookmark saved to the old address no longer opens. Open Boostmail from the Apps section of your Shopify admin sidebar instead, that entry updates itself automatically, or save the new address, https://admin.shopify.com/store/your-store/apps/boostmail, replacing your-store with your store handle. Nothing else changed: your account, data, subscribers, and plan are exactly as they were, and you do not need to reinstall.
