Porkbun for cold email domains (2026): prices, renewals, verdict

What Porkbun is

Porkbun is an ICANN-accredited domain registrar run by Porkbun LLC from the Portland, Oregon area, with a reputation for low prices, free extras and a sense of humour about pigs. For cold email it matters because every campaign needs secondary domains, bought cheaply, kept private, forwarded somewhere sensible and managed in bulk, and Porkbun does all four. It also sells email hosting, SSL, and static and WordPress hosting, offers a documented REST API, and publishes registration, renewal and transfer prices side by side for every extension, which is rarer than it should be.

Porkbun pricing

Prices are per domain per year in US dollars with ICANN fees included. A .com costs $11.08 to register, $11.08 to renew and $11.08 to transfer, with no first-year discount to unwind later. A .net is $12.52 and a .org $7.98 for the first year then $11.84. Many other extensions carry first-year sales with much higher renewals: .co $15.76 then $31.20, .io $28.12 then $51.80, .info $3.60 then $22.14, .pro $3.09 then $22.14, .biz $6.69 then $19.05 and .xyz $2.04 then $14.21. Every domain includes WHOIS privacy, an SSL certificate, email forwarding for 20 addresses, URL forwarding and DNS. Porkbun Email, a hosted business inbox with 10 GB and IMAP, costs $36 a year and is free for 15 days with a new domain.

Domains register for one year and renew automatically unless you switch auto-renew off, and the registration agreement puts the job of tracking expiry on you. Refunds follow the registries’ grace periods: Porkbun gives 96 hours after a registration or renewal in which eligible domains can be deleted and refunded from inside the account, after which it cannot recover its costs and offers nothing, and it notes that some extensions are excluded and that no refund is guaranteed.

Setup, DNS and the API

Buying is the usual cart, with bulk search for lists of names. DNS is free and runs on Cloudflare’s network with DNSSEC, and you can point the domain at your own nameservers instead if your inbox provider wants control. SPF, DKIM and DMARC are yours to add, or your provider’s to add through the API, which covers registration, renewal, transfer, DNS, SSL, forwarding and the aftermarket in a clean JSON format. URL forwarding sends visitors from an outreach domain to your main site, and email forwarding routes replies to a real inbox when you are not hosting mailboxes on the domain. Support runs by email, chat and phone 365 days a year.

Cold email considerations

Two rules fall out of the price list. First, buy .com, with .net as the fallback: they are priced flat, they are what every mailbox provider expects to see, and the cheap first-year extensions are both distrusted by filters and expensive to renew. Second, turn WHOIS privacy on, forward the domain to your main site and keep it for at least a year, because a domain that changes hands or expires mid-campaign takes its reputation with it. Porkbun does not sell cold email inboxes, warm-up or placement tests; it sells the ground they stand on.

Who Porkbun is for, and who should look elsewhere

Porkbun suits anyone buying secondary domains for cold email who wants flat .com pricing, free privacy and forwarding, and an API to manage a fleet. It is a poor fit for buying bargain extensions for outreach, or for anyone expecting the registrar to supply inboxes or deliverability. Cloudflare sells .com at cost for $10.46 with free DNS, but gives no refunds and requires its own nameservers. The email platforms and registrars category lists the other hosting-side tools in this directory. Spaceship undercuts both on .com, at $8.88 the first year and $9.98 to renew, with a five-day discretionary refund window.

Using Porkbun with PureMail

PureMail asks you to bring your own domains and names Porkbun among the registrars it works with. Register the outreach domains at Porkbun with WHOIS privacy on, set URL forwarding to your main site, and hand the domains to PureMail, whose team configures SPF, DKIM, DMARC and MX for the Google Workspace or Microsoft 365 inboxes it supplies. Keep auto-renew on for domains you intend to keep sending from, and switch it off before a domain you are retiring comes up for renewal.
