Sending Standards

What we do for you

• Country rules. Every contact is checked against the law of the country they are in, before anything is sent. See section 1.
• The source of every address. Each lead records where it came from: your upload, your CRM, our database, or the page where the address was published.
• One-click opt-out on every email. It can't be removed, and an opt-out is permanent. See section 4.
• A global do-not-contact list. A person who asks Sellvance to stop is never emailed again from any Sellvance workspace.
• Automatic pauses. Sending stops on its own when bounces or complaints climb. See section 7.

Sellvance is built for honest, relevant B2B outreach. We help you reach the right people at the right companies, in a way that is legal where they are, respectful of their inbox, and safe for your domains.

Most of these checks run on their own. Some of them will leave contacts out of a campaign or pause sending. When that happens, we tell you which rule fired and why. The rules are the same in the web app, the API and the MCP server, so an AI agent working for you meets exactly the same checks you do.

Three promises sit behind everything on this page:

1. We follow the law where your prospects are. Each country has its own rules for business email. Sellvance applies them automatically, so you don't have to research each one.
2. Every message is honest and easy to stop. Your real company name, your address and a one-click opt-out are on every email. Opt-outs are permanent.
3. We protect your reputation and ours. Sending caps, verified data and automatic pauses keep your domains healthy and your brand off blocklists.

1. The recipient's country decides

Email law is written for the person who receives the email, not the person who sends it. A rule in Germany applies to a German recipient even if you are in the US. No law sets a safe volume: one email is regulated the same way as ten thousand.

So every contact is checked against the rules of their country. Countries fall into three groups.

Countries where business email is allowed with a clear opt-out

Examples: the United States, the United Kingdom, Ireland and Portugal. You can email business contacts here, as long as the email says who you are, gives your address, and lets the person opt out. Sellvance adds all three to every email.

Sole traders and freelancers are a common exception. In many of these countries the law treats them as private individuals, so they need consent first. They are left out unless you have it.

Countries that need evidence about the address

Examples: Canada, Australia, New Zealand, Japan, the Netherlands and Slovakia, and with their own conditions France, Finland and Belgium. Here business email is allowed only when the address was published by the business itself, and the offer is relevant to the person's job. In Belgium only role addresses, such as info@ or sales@, qualify.

A contact in these countries is emailed only when we have a record of where the address was published and why the offer fits their role. Without that record, the contact is left out. A guessed address is not evidence.

Countries that require prior consent

Examples: Germany, Austria, Italy, Spain, Poland, Denmark, Greece, Lithuania, Malta, the Czech Republic, Romania, Switzerland, South Korea and Israel. Here even a business needs to agree before you send it a promotional email.

A contact in these countries is emailed only if you upload a consent record for them: when they agreed, how, and what they agreed to. You must be able to prove every record you upload, and we may ask you to. See section 4 of the Acceptable Use Policy. Your existing customers are the exception the law makes: you may email people who bought from you about similar products, as long as they can opt out, and every email we send lets them. Mark them as customers (or import them as “Our own customers”). Without consent or a customer relationship you can still reach these people by phone or on LinkedIn.

Countries whose rules we have not confirmed yet are treated the same way, until we have.

Why: in several countries fines for emailing without a lawful basis are counted per email. Leaving a contact out costs you one reply. Sending to them can cost far more.

2. How we decide which country a contact is in

We look at three sources:

• the company's headquarters, from our company data;
• the email domain, when it has a country ending such as .de or .fr;
• the country you give us for the contact, for example in a CSV column.

If the sources disagree, the stricter rule wins. The country you give us can make the rule stricter, but it can't make it looser when our data says otherwise.

If we can't tell the country at all, the contact is not emailed until it's clarified. You can fix that by adding the country, or by matching the contact to a company in our database.

Why: a wrong guess in the lenient direction is the one that gets you fined. Waiting for a clear answer costs a few days at most.

3. Every email says who sent it

Sellvance adds a footer to every email with your legal company name, your postal address and a line on how to opt out. You can't remove it. Before your first campaign, you set your legal name and address in the workspace.

Why: almost every email law, from the US to Japan, requires a real sender and a real address. An email without them breaks the law even where cold email is otherwise allowed.

4. One click to opt out, and it's permanent

• Every email has a one-click unsubscribe link, and the headers that make Gmail and Outlook show their own unsubscribe button.
• A reply such as “stop”, “unsubscribe” or “remove me”, in any common language, counts as an opt-out too.
• An opt-out takes effect immediately. It applies to your whole workspace, stops every campaign for that person, and stays in place. Only a new, provable consent from that person lifts it.
• We also keep a global do-not-contact list. A person who asks Sellvance to stop is never emailed again from any Sellvance workspace.

Why: the right to opt out is the one rule every country shares, and ignored opt-outs drive most spam complaints. A complaint hurts your domain far more than an unsubscribe does.

5. Business addresses only

Personal mailboxes, such as gmail.com, outlook.com, yahoo.com or icloud.com addresses, are emailed only when the person verifiably uses the address as their business contact. Any one of these shows it:

• the person is already your customer at that address;
• you hold a consent record for the address;
• the person publishes the address as their business contact, for example on their own website or business listing;
• you confirm the business use on the lead, with evidence: a link, or a short note such as “address on our invoices since 2019”. For contacts from the Sellvance database the evidence must be a link.

Without one of these, campaigns don’t email the address. A personal mailbox also says nothing about where the person is, so the lead still needs a country.

Why: a personal address usually belongs to a private individual, and in most countries private individuals must consent before any marketing email. Sellvance is for business-to-business outreach, so our Terms allow such an address only when it is clearly used for business. Gmail and Yahoo also apply their strictest sender rules to mail that reaches their users.

6. Sending caps

• Each mailbox sends up to 30 emails a day by default. You can raise it to a maximum of 50.
• A sequence has at most five emails per person.

Why: mailbox providers trust a steady, modest pace from a real mailbox. Sudden spikes are a classic spam signal and can get a new domain blocked quickly. In several countries each email is a separate offence, so fewer follow-ups also means less exposure.

7. Automatic pauses

We watch every mailbox, domain and campaign. When a signal crosses a threshold, sending pauses on its own and we tell you why.

If a workspace is paused again and again, we suspend its sending until we have reviewed it with you.

Why: Gmail asks senders to keep complaints below 0.1% and penalises them from 0.3%. A high bounce rate tells providers the list is old or bought. Pausing early keeps a fixable problem from becoming a burned domain, and protects the other customers who share our infrastructure.

8. Domain authentication before the first send

A domain can't send until SPF, DKIM and DMARC are published and verified. On domains managed by Sellvance we set them up for you. We also check sending domains against public blocklists.

Why: unauthenticated mail is the first thing Gmail, Yahoo and Microsoft reject, and DMARC is what stops others from sending mail in your name.

9. Report abuse

If you received an email sent through Sellvance that you think breaks these standards, write to abuse@sellvance.com or use our abuse report form. A person reviews every report, and pauses the sender's workspace while a report that holds up is looked into. Reports are not acted on automatically, so a fake one can't switch off a legitimate sender.

10. Remove yourself

If you don't want to be contacted by any Sellvance customer, use Remove my data. You don't need an account. We confirm the request by email, add you to our global do-not-contact list, and remove or suppress your record in our company database.

Not legal advice

This page explains how Sellvance works. It is not legal advice, and these checks don't replace your own duties under the law of each country you email. You stay responsible for your lists, your messages and your consent records, as set out in our Terms of Service and Acceptable Use Policy. We update these standards as laws and mailbox-provider rules change.
