Meet E-Warmup. Warmup is the start. Not the whole product.

On entry price, yes: TrulyInbox Starter is $29 per month against $49 for E-Warmup Basic. But TrulyInbox charges for total emails sent, so Starter buys 200 warmup emails per day shared across all accounts. Priced per warmup email at full daily allowance, Starter is about $0.0048 and E-Warmup Basic about $0.0022, roughly half. At $99 each, TrulyInbox Growth works out to about $0.0033 per email and E-Warmup Growth about $0.00055, around 6x cheaper.

With a shared pool, one daily limit is split across every account you connect. TrulyInbox Starter’s 200 emails per day gives you about 40 per mailbox at 5 accounts, and about 1 per mailbox at 200 accounts. E-Warmup sets volume per mailbox, so Basic’s 5 mailboxes each get up to 150 per day, for 750 in total. Adding a mailbox adds capacity instead of diluting what you already have.

No. Unlimited refers to how many accounts you can connect, not how much warmup each one gets. The daily volume is fixed per plan and shared, so the more inboxes you add, the less each one warms up. E-Warmup’s per-mailbox allowance grows with every mailbox you add.

Yes. E-Warmup monitors 100+ domain blacklists with automatic delisting on Basic and above, and includes monthly inbox placement tests on every plan, starting at 5 on Free Forever. In our comparison, TrulyInbox doesn’t list these features.

Warmup builds reputation, but cold outreach also depends on authentication, blacklist status and bounce rates. E-Warmup tracks those alongside warmup, so you can catch a problem before it hits a live campaign. It also gives every mailbox its own warmup volume, which matters once you scale past a few inboxes.

Premium covers 40 mailboxes at up to 500 warmup emails per day each. Growth and Premium can add extra mailboxes at $9 each, and the High Volume plan offers unlimited mailboxes through support.

If you run one or two mailboxes at low warmup volume and only need warmup, TrulyInbox’s lower entry price can make sense. It also fits if you already use separate tools for monitoring and testing. Once you connect more inboxes, the shared pool dilutes volume per mailbox, and that’s where E-Warmup’s per-mailbox model pulls ahead.
