KindredBlast — a one-time-payment email sending platform built as an alternative to monthly outreach subscriptions. Bulk sending and email automation from your own domain and paid email / Google Workspace, with reputation-focused sending and no recurring platform fee on top of the domain and mailbox costs you already pay.
Cold-email tools charge a monthly subscription on top of the domain and mailbox costs you already pay, and the fee keeps coming whether or not you send a campaign that month.
A one-time-payment sending platform. Bulk sending and email automation from your own domain and paid email or Google Workspace, with reputation-focused sending and no recurring platform fee.
Worked out from the monthly prices of Instantly, Smartlead, Apollo and lemlist in the table below: the range is the cheapest to the dearest of them, over 12 and 36 months.
| Platform | Recurring cost |
|---|---|
| Instantly | ~$43.83–$50.25/mo |
| Apollo | ~$55.83–$62.25/mo |
| lemlist | ~$65.83–$72.25/mo |
| Smartlead | ~$45.83–$52.25/mo |
Those figures are per month, before the long-term cost of paying them month after month.
The idea is simple:
Sending from your own domain through mailboxes you already pay for keeps the sending reputation yours rather than shared, and it removes the platform from the recurring column of the spreadsheet. The demo walks through the interface and how the platform fits into a more cost-efficient outreach setup.
Sending infrastructure only performs if the authentication underneath it is correct. That layer — SPF, DKIM, DMARC, sending and tracking domains — is covered in cold email deliverability setup.
