Getting started with MailToaster

If you're a Reply user with a paid subscription, you can use MailToaster to warm up your email accounts. Before you start, you'll need to link your Reply and MailToaster accounts. 1. Go to Email WarmUp under the Sequences page in Reply. 2. Click Link existing user if you already have a MailToaster account, or Register new user to create one. 3. Log in with your MailToaster credentials or sign up for a new account. 4. Add your email accounts to MailToaster. Once your subscription is linked, MailToaster will automatically give one warm-up seat for each mailbox connected in Reply. Single login for Reply and MailToaster Reply and MailToaster support single login, so you can access MailToaster directly through your Reply account. Once your accounts are linked, you can open MailToaster from the Email Warmup page in Reply. 💡 Important: You need a Reply account to access MailToaster. Logging in to MailToaster without a Reply account is not possible. Your MailToaster account will be tied to your Reply.io login. For example, if your MailToaster login is [email protected] but your Reply login is [email protected], after linking, you'll only be able to access MailToaster with [email protected]. If you want to keep your Reply and MailToaster accounts separate, you'll need to create a new Reply account that matches your MailToaster login. For example, if your MailToaster login is [email protected], create a trial Reply account under [email protected] and link it to MailToaster. MailToaster for organizations If you have multiple teams within your organization, here's how it works: - Each Reply team has its own MailToaster team. For example, if your organization has three teams, each one has a separate MailToaster team. - The MailToaster team is connected to the organization owner's login, but all members of the Reply team can access it. - Team members don't have separate MailToaster accounts. Their mailboxes are synced to the MailToaster team linked to the organization owner's account. - Any team member can access MailToaster by clicking Email WarmUp. - The first person from a Reply team to open Email Warm-up creates a MailToaster team with the same name as the Reply team. - If you remove a team from Reply, its MailToaster team is also removed. - If you belong to multiple Reply teams, MailToaster opens in the team you used most recently. You can switch between teams and access only those you're a member of.

Syncing email accounts to Mailtoaster

Once you've linked the subscription with MailToaster, you can sync mailboxes from Reply to MailToaster and start warming them up right away. In this article, we'll show you how to add both existing and new mailboxes to MailToaster, whether manually or via CSV. Connecting existing mailboxes To connect an existing mailbox to MailToaster: 1. Go to Settings → Email Accounts in Reply. 2. Open the mailbox you want to connect. 3. Switch to the WarmUp tab. 4. Click Connect. 5. Fill in any missing details (e.g., for Gmail, you'll need an app-specific password). 6. Click Save. The mailbox will then be automatically added and activated in MailToaster. Connecting new mailboxes When you add a new mailbox in Reply, you can enable the Import to MailToaster checkbox to automatically add and activate the mailbox in MailToaster. 💡 The Import to MailToaster option only works for mailboxes added to Reply after you've linked your subscription. If you added mailboxes before linking, they won't sync automatically. You'll need to connect them manually using the Connect button in Warm-up settings or upload them via CSV in MailToaster. Here's a breakdown of how it works for different mailbox types: Gmail When you add a Gmail mailbox in Reply, Google will prompt you to authorize the connection. After granting permission, you'll see a 'Connect to MailToaster' pop-up. The host and port fields will be filled in automatically, but you'll need to enable 2-factor authentication, enter your app-generated password, and click 'Save'. Outlook When you add an Outlook mailbox in Reply, it's automatically synced to MailToaster. No extra setup is needed. Other Provider If you choose Other provider and fill in all required fields in Reply, the same information will be automatically sent to MailToaster. Exchange Single Click and On-Premises These mailbox types are not supported for MailToaster warm-up at the moment. Import from CSV When you add mailboxes using a CSV file in Reply, warm-up settings like daily limits and starting amounts are already preconfigured. These mailboxes are automatically added to MailToaster with the same settings and activated right away. If you don't want mailboxes to be activated in MailToaster immediately, simply uncheck the Import to MailToaster option when adding them in Reply. You can then add the mailboxes to MailToaster later, either one by one or by uploading a CSV file. If you sign up for Reply and use MailToaster, your MailToaster subscription will be automatically created when you create a new MailToaster account from within Reply. If you already have a paid Reply subscription with connected mailboxes, you don't need to pay anything extra to use MailToaster.
