TrulyInbox Alternative: Free Warm-Up for More Mailboxes

BobWork is a practical TrulyInbox alternative if you need more than one free warm-up mailbox: TrulyInbox lists 1 free email account at 10 warm-up emails/day, while BobWork is free for up to 20 mailboxes. If you ignore that limit, a small team can move from free to paid quickly. This guide compares costs, provider fit, pool model and switching steps, including the free warm-up tool.

Is BobWork a TrulyInbox alternative?

Yes, if your main constraint is free warm-up capacity. TrulyInbox and BobWork Email Warm-up both offer a free-forever option. The difference is the limit.

TrulyInbox, a Saleshandy product, lists a free plan with 1 email account, 10 warm-up emails per day, basic deliverability tracking and no card. BobWork Email Warm-up is free for up to 20 mailboxes per account, with no card and no time limit.

The main trade-off is provider support. TrulyInbox lists Outlook support in the pricing-page facts used here. BobWork does not support Outlook yet because Microsoft requires OAuth. If your mailbox is Outlook or Microsoft 365, that may decide the comparison.

TrulyInbox facts in this article were verified from the vendor’s pages on 4 October 2026. Check the current pricing page before you buy.

Among standalone warm-up tools, only TrulyInbox and BobWork Email Warm-up offer a free-forever plan in the facts we track. TrulyInbox gives 1 account at 10 emails/day. BobWork gives up to 20 mailboxes, each starting at 3/day and ramping toward 30/day by default.

If you are comparing more free plans, use the broader free email warm-up tools comparison. If your decision is mainly cost, the cheapest warm-up per mailbox table is faster.

How do the plans compare?

Use the numbers before you compare features. A free plan for one inbox is very different from a free plan for a team, agency or founder running several sender identities.

This table is not a claim that one product is better for every team. TrulyInbox is stronger when you need Outlook support or prefer the Saleshandy ecosystem. BobWork is stronger when you need several supported mailboxes warmed without paying.

When should you keep TrulyInbox?

Keep TrulyInbox if you use Outlook. BobWork does not support Outlook or Microsoft 365 yet. Do not force an unsupported provider into a warm-up workflow.

Keep TrulyInbox if one free mailbox is enough. If you have one sender and 10 warm-up emails/day fits your plan, switching may create work without solving a real problem.

Keep TrulyInbox if you already use Saleshandy and prefer one ecosystem. Fewer dashboards, fewer permissions and one vendor relationship can matter for operations and procurement.

Keep TrulyInbox if you prefer its stated network profile. The facts we track list a peer network of 40,000+ real accounts, with Google, Microsoft and Zoho counts. BobWork also runs a shared warm-up network by default, but we do not publish a network-size number in prose; the live count appears in the dashboard.

Keep TrulyInbox if its Starter limits fit your process. The facts list Starter at $22/month on annual billing or $29 monthly, with unlimited accounts and 200/day. Compare that with your real mailbox count, not only the headline price.

Do not assume feature parity. If your workflow depends on a Saleshandy feature, confirm it inside Saleshandy before switching.

When is BobWork better?

BobWork is better when you need free capacity across several supported mailboxes. Up to 20 mailboxes per account are free, with no card and no time limit. That helps small teams, agencies testing domains and founders running multiple sender identities.

The warm-up schedule is explicit. Each mailbox starts at 3 emails/day, adds 2 per day, and caps at 30/day by default. You can edit the cap per mailbox up to 100. Weekends run at 30% of weekday volume.

Sends are spread across 09:00–18:00 in the mailbox’s own time zone. The engine decides every 15 minutes with randomness. A pair never writes to each other twice within 3 hours. Peers on a different domain or provider are picked twice as often.

About 40% of received warm-up mail gets a reply. Threads end after 3 messages. Content is plain-text office talk with no links and no images. Users do not write the warm-up text, so nobody can push spam or links through the network.

The pool model is flexible. BobWork uses a shared warm-up network by default, so one mailbox is enough to start. If you prefer isolation, switch to private pool in the dashboard under Mailbox pool → Pool mode. Private mode needs at least two mailboxes.

BobWork supports Gmail and Google Workspace, Zoho Mail, Lark Mail, Yahoo Mail, iCloud Mail, Amazon SES, SendGrid, Mailgun and any IMAP+SMTP mailbox. It does not support Outlook yet.

For Google, BobWork can connect through Google sign-in with the gmail.modify scope. Google shows an unverified-app notice because BobWork has not completed the CASA audit. You can also use IMAP with an app password where that fits your setup.

For Zoho, BobWork supports the Zoho Mail API through a Self Client code, including the free plan. It can also use IMAP on Mail Lite and higher. If Zoho is your main provider, use the Zoho warm-up setup guide.

BobWork checks SPF, DKIM and DMARC daily through DNS and shows results per domain. It looks for common DKIM selectors including google, zmail, default, selector1, selector2, k1, s1, mail, dkim, lark, feishu and zoho.

Warm-up mail found in Spam is moved to Inbox, marked read, labelled Warm-up, and archived after 24 hours. Only mail carrying the engine’s own hidden header, or a known subject for Zoho API senders, is touched. Real mail is never read, moved or answered.

A mailbox is marked ready for outbound after 14+ days warming, a 7-day spam rate of 3% or lower, and at least 30 warm-up emails received. That does not guarantee inbox placement. It gives you a checkpoint before scaling.

What does switching cost?

The cheapest option depends on mailbox count. TrulyInbox has a free plan, but it is limited to 1 email account and 10 warm-up emails/day. BobWork stays free through 20 mailboxes.

The table below uses the annual-billing TrulyInbox Starter price because it is the lower listed paid price. The monthly Starter price is $29/month.

There is no hidden calculation for BobWork at 20 mailboxes. The first 20 active mailboxes are free. Each active mailbox above 20 costs $2/month, billed by Stripe, prorated and cancellable any time. Extras pause without billing.

Cost is not the only limit. If you need Outlook, BobWork should not be your choice today. If you need several Gmail, Zoho, Lark, Yahoo, iCloud, SES, SendGrid, Mailgun or IMAP+SMTP mailboxes, BobWork is usually the lower-cost route.

How do you switch safely?

Do not run two warm-up tools on the same mailbox at the same time. Stop warm-up in the old tool first, wait for scheduled actions to finish, then connect the mailbox to the new tool.

1. List your mailboxes

Create a sheet with mailbox, provider, domain, current daily outreach volume and warm-up status. Mark Outlook and Microsoft 365 mailboxes separately. Those should stay on TrulyInbox or another Microsoft-compatible tool for now.

Mark new domains too. A new domain typically needs 3–4 weeks of warming before meaningful cold outreach. An existing domain with good history usually needs at least 14 days.

2. Check DNS first

Check SPF, DKIM and DMARC before connecting warm-up. Warm-up cannot fix broken authentication. It can only help after the technical setup is right.

For Google senders, review Google’s sender guidance, including the requirement to keep spam complaint rates under 0.1% and never at or above 0.3%: Email sender guidelines.

For Yahoo, review Yahoo sender requirements. For Microsoft-hosted mailboxes, use Microsoft’s own authentication documentation, but remember BobWork does not support Outlook yet.

3. Connect the mailbox

Create a BobWork account with an email code. There is no password and no card for the free plan.

For Gmail or Google Workspace, use Google sign-in or IMAP with an app password. Google sign-in requests gmail.modify. You may see Google’s unverified-app notice because BobWork has not completed the CASA audit.

For Zoho Mail, use the Zoho Mail API with a Self Client code, or IMAP on Mail Lite and higher. Zoho’s API route works on the free plan. Zoho’s current documentation is here: Zoho Mail API.

For Lark, use IMAP plus a mail-client password. For Yahoo Mail and iCloud Mail, use IMAP plus an app password. For Amazon SES, SendGrid and Mailgun, use the platform’s SMTP credentials for sending and a receiving inbox over IMAP.

4. Choose pool mode

Leave the default shared network on if you want one mailbox to start immediately. In shared mode, every active mailbox on the service exchanges warm-up emails with other active mailboxes across accounts.

Choose private pool if you want only your own mailboxes to write to each other. Go to Mailbox pool → Pool mode in the dashboard. Private mode needs at least two mailboxes. Nobody outside your account receives your addresses in private mode.

The free pool does this step automatically in shared mode. It selects peers, spreads sends during working hours, replies to some messages and rescues engine-generated warm-up mail from Spam.

5. Set conservative limits

Keep the default ramp unless you have a reason to edit it. BobWork starts at 3 emails/day, adds 2 per day, and caps at 30/day by default. The cap is editable per mailbox up to 100, but higher is not automatically better.

During active campaigns, keep warm-up around 10–15/day. Keep real outreach around 30–50/day per mailbox. Add mailboxes rather than forcing one mailbox to carry all volume.

If a mailbox rises above a 5% spam rate, pause it for a few days. Fix authentication, content, list quality and sending volume before you resume.

6. Wait for readiness

Do not treat day one as proof. Wait until the mailbox has warmed for at least 14 days, has a 7-day spam rate of 3% or lower, and has received at least 30 warm-up emails.

That is BobWork’s ready-for-outbound gate. It is not a guarantee. It helps you avoid launching cold outreach from a mailbox with obvious placement problems.

If you are warming a new domain, use a longer ramp. The new domain warm-up guide gives a 21-day plan, and the warm-up schedule guide shows daily volume examples.

What mistakes should you avoid?

Do not change everything at once. If you move warm-up tools, rewrite outreach copy, change domains, raise volume and upload a new list on the same day, you will not know which change caused a problem.

Do not use warm-up to compensate for bad sending. Warm-up helps create normal mailbox activity. It does not make scraped lists safe, fix misleading subject lines or override authentication failures.

Do not ignore complaint rates. For Google, the published target is to keep spam complaints under 0.1% and avoid reaching 0.3% or higher. That is about real recipient complaints, not only warm-up spam placement.

Do not send links and attachments too early. Early outreach should be plain and controlled. BobWork warm-up mail is plain text with no links or images for the same reason.

Do not overvalue daily warm-up volume. A larger number is not always safer. If real outreach is low, warm-up should not be much higher than normal sending.

Do not skip provider rules. SES, SendGrid and Mailgun need correct SMTP credentials and a real receiving inbox over IMAP. For SendGrid, review the provider’s sender authentication documentation: SendGrid sender authentication.

Do this now

Use this checklist before you switch. It stops you from moving a mailbox that should stay where it is.

If you need one free Outlook-compatible inbox, TrulyInbox may be the better fit. If you need to warm several supported mailboxes without paying, start with BobWork Email Warm-up, keep the default ramp and switch only the mailboxes that match its provider coverage.
