Frequently asked questions

Postfaro is a managed SMTP service for bulk email. We give your company a separate, fully authenticated sending domain and run the sending infrastructure behind it. You keep your contacts in your own CRM, Outlook or WordPress newsletter plugin and send through our SMTP server. Up to 5,000 emails a day, $99 a year.

Companies that send newsletters, price lists, event invitations or campaigns to a few thousand people — more than a normal mailbox should send, but without wanting a full email-marketing platform. It suits especially companies whose sending is seasonal: trade-fair weeks, season openings, campaign periods.

No. We don’t have an editor, a contact database or campaign reports. You design and send in the tool you already use; we make sure what you send is delivered properly. If you want everything in one platform, an email-marketing service may suit you better.

No. Your lists never leave your own tools. Each message passes through our servers only to be delivered.

Any tool that can send through an SMTP server with a username and password. We have step-by-step guides for Vtiger CRM, Microsoft Outlook (Word mail merge), FluentCRM with FluentSMTP, Mailster and MailPoet, plus generic SMTP settings for everything else.

Because your main domain carries your everyday business: quotes, invoices, replies to customers. If a campaign ever triggers complaints or bounces, mailbox providers may start filtering mail from the sending domain. That must never be the domain your team relies on every day. A separate sending domain keeps the risk away from it.

Three ways to get a sending domain: A — we register a new .com or .net in your name; B — you point a spare domain you already own to our nameservers; C — you delegate a subdomain like news.yourcompany.com with two DNS records. See the comparison.

In path A, nothing at all. In path B, you change two nameserver values at your registrar. In path C, you add two NS records at your DNS provider. That’s all — we create every other record.

You do. It is registered in your company’s name. You’ll receive a confirmation email from our registrar partner, which you must click within 15 days — domain rules require it.

Yes. The domain’s web address redirects to your main website by default, and you can add your own website records (A, AAAA, CNAME) in the DNS panel.

Most do. If yours doesn’t, choose path A — it needs no DNS changes at all — or contact us.

Nothing breaks. We accept everything your tool sends and queue whatever doesn’t fit into today. Each following day, the next 5,000 go out. You receive an email such as “22,000 emails queued — last send on 18 March”, and you can follow or cancel the queue in your panel.

Per account. All your sender addresses together share 5,000 per day.

No — it’s “use it or lose it”. In return there are no monthly quotas and no credits that expire.

That’s warm-up. Mailbox providers distrust a new sender that suddenly sends thousands of emails, so your daily limit starts low and rises step by step — typically 3–4 weeks for a brand-new domain, 1–2 weeks for an established one. You can still send any amount; it just queues for longer.

No. Those emails must arrive within seconds, but Postfaro queues and paces bulk email. Keep transactional and everyday email on your current mail server. Our guides show how to route only campaign email to Postfaro (for example with FluentSMTP’s routing by sender address).

As many as you like, for example news@, events@, offers@. Each gets its own username and password, which can only send as that address. A few addresses such as postmaster@ and abuse@ are reserved.

Replies to each sender address are forwarded to the mailbox you choose for it — for example your sales team’s normal inbox.

Addresses we will not send to: they bounced permanently, the recipient marked your email as spam, or they unsubscribed with the one-click button. We drop messages to them and list them in your panel with the reason, so you can clean them out of your own tool.

To protect your domain. Sending pauses automatically if more than 2% of your messages bounce or more than 0.1% of recipients mark them as spam, or if our checks find phishing or malware. You receive an email with the reason and the next steps. Queued messages wait; nothing is lost.

We set up everything that mailbox providers check on the technical side: SPF, DKIM, DMARC with alignment, one-click unsubscribe, a clean sending infrastructure, warm-up and pacing. But the final decision is always made by the receiving provider, based also on your list and your content. Opted-in, recently engaged contacts and honest, relevant content give the best results. Nobody can honestly guarantee inbox placement — and we don’t.

Since 2024, Gmail and Yahoo require bulk senders (Google defines them as senders of around 5,000 or more messages a day to personal Gmail accounts) to: authenticate with SPF and DKIM, publish a DMARC policy with the From domain aligned, offer one-click unsubscribe and process unsubscribes within two days, and keep spam complaint rates low — Google says below 0.3%. Microsoft introduced similar requirements for Outlook.com in 2025. Every Postfaro account is set up to meet these technical requirements from day one. Keeping complaint rates low is in your hands — our automatic pause at 0.1% helps you stay well below the limit.

Yes, in practice. Basic authentication (SPF or DKIM), valid reverse DNS, TLS and low spam rates apply to all senders, and providers count volume across your whole domain, including subdomains. Being fully set up from the start avoids surprises later.

No. Purchased, rented and scraped lists are prohibited by our Acceptable Use Policy — they cause bounces and complaints, damage reputation for everyone, and are illegal in many countries. You must have permission from every recipient.

You are responsible for having consent and following the laws of your recipients’ countries. In short: get permission, identify yourself, include your postal address where required, and make unsubscribing easy. Our Acceptable Use Policy has a short overview. For your own situation, ask your legal adviser.

As little as possible. Recipient addresses and message content are processed only to deliver your email — including while messages wait in the queue. The only recipient data we keep long-term is the list of addresses that must never be emailed again (bounces, complaints, unsubscribes), so that we can protect them.

Our sending servers are located in Turkey. For customers in the EU and UK, transfers are covered by Standard Contractual Clauses in our Data Processing Agreement.

Yes. It’s part of our Terms and applies automatically. You can read it here.

No person reads them as part of normal operation. Our systems automatically check content for spam signals, dangerous links and phishing. If a message is flagged for review, authorised staff may look at it to decide.

No. Postfaro is for businesses, organisations and professionals only. When you sign up, you give your company name and confirm that you are buying for a business.

Through Paddle, our payment partner and Merchant of Record. Paddle handles payment, invoices and taxes. Card and other payment methods are shown at checkout.

Yes, at any time in your panel. Your plan stays active until the end of the paid year and then does not renew. Payments are not refundable once setup has started — see the Refund Policy.

It stays yours — it is registered in your name.

We email you, and Paddle retries. If payment hasn’t succeeded after 7 days, sending pauses until it’s paid.
