    MailDeck is the only cold email infrastructure I trust after testing many others

    Date: Mar 23 2026
    Summary

    After going through multiple cold email infrastructure providers and getting burned every time, misconfigured inboxes, warmups ignored, wrong workspace delivery, I found MailDeck through Sabo's YouTube channel. A year later I'm booking 60–80 meetings a week in the finance niche. The support team actually understands deliverability and infrastructure. They've helped me fine-tune my campaigns and never left me without answers. Best decision I made for outbound.

    Positive

    Correct inbox configuration, proper warmup setup, right workspace delivery, campaign limits handled properly, and genuinely technical support that solves real problems fast.

    Negative

    Onboarding could use more self-serve docs, but support covers the gap well.

    Provider that helped us scale outbound

    Date: Mar 22 2026
    Summary

    Good experience so far. MailDeck has become our primary provider for lead gen team infrastructure and we plan to add more domains as we scale.

    Positive

    Very simple setup process. Prices are way lower than competitors', which matters a lot when you're buying domains in bulk. Support is responsive and always willing to help with any inquiries. Had a question about tenant configuration and got a clear answer in under 10 minutes.

    Negative

    Would be great to see a built in warmup tool or deliverability dashboard added over time.
