What is the best bulk email service for cold email and purchased lists?
The best service is one that explicitly allows purchased and cold lists in its terms — mainstream ESPs like Mailchimp, Constant Contact, and Brevo prohibit them and suspend accounts. Hypermail allows purchased lists for B2B and B2C, and pairs that policy with dedicated IPs, automated warmup, 15+ step list verification, and month-to-month plans from $100 for 100,000 emails.
All Comparisons
Pick your current platform (or the one you're considering).
Hypermail vs. ClickBack
Both allow purchased lists, but ClickBack is B2B-only with a mandatory 12-month contract. Hypermail adds B2C reach, an API, white label, and month-to-month billing.
Hypermail vs. Hotsol
Hotsol runs on the third-party MailWizz script. Hypermail's custom MTA adds full list verification, automated AI warmup, and SHA-256 suppression support.
Hypermail vs. Mailchimp
Mailchimp prohibits purchased lists and suspends accounts that upload them. See the alternative built for prospect data, with pay-per-send pricing.
Hypermail vs. Constant Contact
Constant Contact requires opt-in consent for every recipient. Compare it to a platform designed for compliant cold outreach at high volume.
Hypermail vs. Brevo (Sendinblue)
Brevo bans purchased and rented lists on its shared IPs. Hypermail gives every account dedicated IPs, warmup, and verification instead.
Hypermail vs. Self-Hosted (MailWizz, Interspire, Sendy)
The license is cheap; the infrastructure isn't. What self-hosting bulk email really costs in servers, IPs, warmup, and maintenance hours.
