A deliverability specialist reads every campaign before it goes out. Yours is built in.
Before launch, the review AI reads the campaign the way a consultant would: subject line, language, structure, links, sender alignment, the compliance basics. It hands back a short list — each finding with the reason and the fix, in plain English. It never blocks you. It tells you what a receiver, or a client, would notice while there is still time to change it.
The mistakes that hurt a campaign are obvious the moment someone points at them.
A subject line in capitals. A link to a staging site a client pasted in. A header that is one big image and nothing else. A missing postal address. None of these are hard to fix, and every one of them is sent every week by agencies with talented people — because the person who built the campaign is the least likely to spot it and there was nobody else to look.
Deliverability consultants earn their fee by looking. They read the campaign as a receiver would — is this what unwanted mail looks like? — and as a recipient would — would I open this, would I trust this link? — and they hand back a list. SendTo builds that look into the review step of every campaign.
The findings are written for the person who has to act on them. What the problem is, why it matters, and what to change. You decide whether to change it.
What it reads
The subject line and preheader for tone, urgency and the patterns receivers associate with unwanted mail. The body for structure — text-to-image balance, a readable version with images off, a clear call to action. Every link, for whether it resolves to the sending domain or the client’s site. The sender details, for alignment. The footer, for what the law and receivers expect.

- Links, sender alignment and footer
How it reports
Each finding has three parts: what it found, why it matters to this campaign, and what to change. A finding about a capitalised subject line suggests the rewrite. A finding about an off-domain link names the link and where it should point. The list is short because it only includes things worth your time.
- Finding, reason, fix
- Specific to the campaign in front of it
- Short, ranked, actionable
Where it sits
On the review step, beside the campaign preview, before the launch button. Findings are visible to anyone reviewing the campaign — you, your team, or a client building their own — so the check happens where the decision is made. Re-run it after edits.

A second pair of eyes on every send, for every client.
Fewer wince-in-the-inbox moments
The mistakes a client would spot in their own inbox get caught on the review screen instead. Your reputation with the client is the one that matters most.
Domains protected from avoidable damage
Complaint-trigger language and off-domain links are caught before they cost a domain reputation the client paid for.
Clients who self-serve, safely
A client building their own campaign gets the same specialist read, written plainly enough to act on without calling you.
It caught a link to a staging site the client had pasted in. That one finding paid for the month.
Questions
Does it give a spam score?
No. Scores imply a precision nobody has. It gives findings — what it saw, why it matters, what to change — which is what a consultant would give you.
Can it stop me sending?
No. It informs the decision; you make it. Some findings will not apply to a particular audience, and you are the one who knows.
Does it check links?
Yes. Every link is checked for whether it resolves to the client’s sending domain or their own site, and anything else is called out.
Can clients see the findings?
Yes, on the review step of their own campaigns in your portal, written plainly enough to act on.
Never send the campaign you would have winced at.
A specialist read on the review step, every time, for every client.
