Brandset ensures high email deliverability by enforcing opt-in lists, strong authentication, and gradual volume growth, rejecting cold email and purchased contacts to protect sender reputation.
Brandset Team9 min de leituraGood email deliverability isn't something we can hand you.
It's the result of two commitments working in the same direction — what we protect on our infrastructure side, and what you maintain on yours. When both sides hold up their end, emails reach inboxes. When either one breaks down, the system degrades for everyone.
This post is about that shared responsibility. What we do, what we expect from you, and why the honest version of deliverability is more durable than any technical shortcut.
We manage the infrastructure that sends your emails — the IP addresses, the sending servers, the monitoring systems, and the policies that govern who can use them.
That infrastructure has a reputation. It was built gradually through consistent, responsible sending behavior. And because email reputation is shared across senders on the same infrastructure, every business sending through Brandset affects the conditions every other business sends into.
This is why we're strict about what the platform is built for.
Brandset sends through a tightly controlled environment — monitored IPs, zero tolerance for abuse. From your first send, you benefit from infrastructure that has been carefully protected and monitored over time. You're not starting from zero. But you're also not immune to what you do with it.
New or inactive sending domains should start with smaller audiences and gradually increase volume as they establish a consistent sending history. Brandset guides senders toward this behavior rather than manufacturing engagement or using artificial warm-up activity.
We actively monitor for sending patterns that signal misuse — spam complaints above threshold, hard bounce rates that indicate purchased lists, sudden volume spikes inconsistent with an account's history. Accounts that trigger these signals are reviewed and limited before they can damage the shared infrastructure.
Infrastructure quality matters. But no infrastructure can compensate for the decisions you make about who to email and how.
The most consequential deliverability decisions happen before you hit send — in how your list was built, how your domain is configured, and how consistently you show up for the people who chose to hear from you.
Every contact on your list should have explicitly opted in to receive email from you. Not because they downloaded a resource from a third party. Not because they gave their email for a different purpose. Because they specifically chose to receive communication from your business.
This isn't a legal technicality. It's the foundation of everything that follows. A list built on genuine consent behaves differently — higher open rates, lower complaint rates, better long-term engagement — than a list built any other way. Inbox providers can see the difference in aggregate behavior, and they adjust delivery accordingly.
Purchased lists, scraped addresses, and contacts imported from unrelated sources damage sender reputation quickly and predictably. We don't support these practices, and accounts that use them risk losing access to the platform.
Before sending at any significant volume, your sending domain should have SPF, DKIM, and DMARC records properly configured.
The specific requirements depend on volume and provider. Google classifies senders that send close to 5,000 or more messages per day to personal Gmail accounts as bulk senders. Yahoo also applies additional requirements to bulk senders, but does not publish a specific volume threshold. Microsoft applies its high-volume sender requirements to domains sending more than 5,000 messages per day to Outlook consumer addresses.
For bulk senders, these providers require stronger authentication and other protections, including SPF, DKIM, DMARC, low spam complaint rates, and, where applicable, easy one-click unsubscribe.
If you're a small business sending to a list of 500 or 2,000 subscribers, you may be below the bulk-sender thresholds used by providers that publish one. But baseline sender requirements still apply. Authentication, healthy sending practices, valid DNS configuration, and low complaint rates matter at any volume.
Configuring authentication before you need it is significantly easier than configuring it during a deliverability crisis. Brandset guides you through the setup during onboarding. Most users complete it in under 15 minutes.
A list of 500 engaged subscribers is a healthier sending asset than a list of 5,000 people who haven't opened in eight months.
Sending repeatedly to disengaged contacts can increase the likelihood of complaints and other negative recipient behavior. List size is not the goal. Relevance is.
For Gmail, Google recommends keeping the user-reported spam rate in Postmaster Tools below 0.1% and avoiding rates of 0.3% or higher. Yahoo also requires senders to stay below a 0.3% complaint rate. These are useful guardrails, but they shouldn't be treated as a quota. The goal is to keep complaints as close to zero as reasonably possible.
With 300 subscribers, you don't need a complex segmentation strategy. Pull the contacts who haven't opened or clicked in your last six sends. Send them one honest email — subject line along the lines of "Should I keep sending these?" — with a clear link to stay subscribed and a clear link to leave. Those who click either link are telling you something. Those who don't respond after a second attempt can be removed without hesitation. The whole process takes twenty minutes to set up and protects the deliverability of every campaign that follows.
If you haven't sent in months, or if you're starting a new campaign to a segment you haven't emailed before, don't go from zero to your full list in one send.
Inbox providers interpret sudden volume spikes as suspicious — consistent with compromised accounts or acquired lists. Gradual scaling, starting with your most engaged contacts and expanding from there, looks like what it is: a real business building real relationships.
If you have 800 subscribers and haven't sent in several months, don't assume the best first campaign is one sent to all 800. Start with the subscribers most likely to recognize your name and want the message, then expand gradually. Smaller lists may be able to establish a consistent sending pattern more quickly than larger ones, but there is no universal warm-up schedule that works for every domain.
Consistent sending gives inbox providers a more predictable history than long periods of inactivity followed by sudden bursts of email. You don't need to send more often just for reputation's sake — but when you do send, avoid unnecessary spikes and keep the pattern appropriate for the relationship you have with your audience.
This is what we mean when we say we don't use artificial warm-up. We don't simulate engagement with fake interactions or manufacture signals to manipulate reputation scores. The reputation you build in Brandset is built from real sends, to real people, generating real responses. That kind of reputation holds. The other kind doesn't.
The practices above aren't arbitrary rules. They reflect a specific philosophy about what email marketing is for.
Explicit opt-in only: Not implied consent. Not "they gave us their email for something else." A deliberate choice to receive email from you — every time, no exceptions.
Organic list growth: The platform is built around forms and inbound channels. The mechanism for growing a list is earning subscribers, not acquiring them.
Gradual scaling: New senders don't get to blast. Volume should grow gradually as the sender establishes a consistent sending history with real recipients who chose to receive the email.
Real engagement focus: Not clicks on links designed to inflate metrics, but genuine recipient behavior — replies, clicks, low complaint rates, and healthy list engagement over time.
These aren't aspirational. They're structural. They shape what Brandset lets you do and what it doesn't.
This is the part worth being direct about.
What Brandset is built for | What will get your account reviewed or closed |
|---|---|
Newsletters and nurture sequences | Bought or scraped contact lists |
Inbound leads from websites and forms | Outbound B2B cold prospecting at scale |
Content-driven campaigns to opt-in subscribers | Mass domain warm-up for cold email |
Welcome and onboarding sequences | Sending to contacts who never opted in |
Brandset is not a cold email tool. It's not built for purchased lists, scraped contacts, outbound B2B prospecting, or warming a domain to support mass cold outreach. If you use Brandset that way, the account gets limited or closed — not as a loophole, but as a policy that's actively enforced.
This matters beyond the obvious reason. Email deliverability is a shared resource. Every sender on Brandset affects the infrastructure everyone uses. A platform with clean senders has better deliverability for all of them. A platform that tolerates abuse has worse deliverability for everyone — including the people doing everything right.
Keeping bad actors out isn't just about enforcing terms. It's how the platform protects the senders who are building something real.
The shared responsibility model works because its incentives are aligned.
We benefit from protecting the infrastructure — our reputation depends on it. You benefit from following the practices — your deliverability depends on it. The people on your list benefit from the commitment to consent — their inbox isn't polluted with email they didn't ask for.
When that alignment holds, the system produces exactly what it's supposed to: relevant email reaching people who want it, in inboxes they actually check.
That's the honest version of email deliverability. Not a feature you configure once. Not a technical shortcut that eventually stops working. A practice that compounds over time because it's built on something real.
Brandset is built for businesses that want to do email marketing properly — not because it's required, but because it produces better results and better relationships over time.
If you're building a newsletter, a welcome sequence, a nurture flow, or a re-engagement campaign for people who chose to hear from you — this is the platform for that work.
If you're looking for a tool to send cold outreach at scale or warm up a domain for bulk prospecting — this isn't it. And we'd rather be clear about that than have you find out after the fact.
