Send from the mailbox you already own
Every hosted cold-email tool puts your sending inside a shared pool of IP addresses. Your reply rate then depends partly on what a stranger in that pool did last Tuesday. Lead Scraper sends through your own Mail account instead.

The problem with a shared sending pool
A sequencer that sends on your behalf has to send from somewhere. For the hosted tools that somewhere is infrastructure shared with every other customer on your plan tier. It works until it doesn’t: someone blasts a bought list, the pool’s reputation drops, and mail from people who did nothing wrong starts landing in spam.
You cannot see it happen. There is no error, no bounce, no notification — your open rate simply gets worse and you assume your copy got stale. The reputation you are borrowing was never yours to protect.
What sending from your own mailbox changes
- The mail goes out from the address you already use, through the account already configured in Mail on your Mac.
- SPF and DKIM align to your own domain, because it is your own domain. Your sending reputation is yours to earn or to wreck — nobody else can spend it.
- The prospect sees a reply-to that matches the sender, on a domain they can look up. Nothing routes through a third party's tracking domain.
- Replies arrive in your inbox, where you already read mail, rather than in a dashboard you have to remember to open.
- Your sent folder is the record. If you stop using the app, the history of what you sent does not leave with it.
Volume is the trade, and it is deliberate
Your own mailbox is not built to send ten thousand emails a day, and Lead Scraper does not pretend otherwise — it paces sends rather than emptying the queue at once. If your plan is high-volume blasting to a bought list, this is the wrong tool and a shared pool is genuinely what you want.
If your plan is thirty well-aimed emails a week to businesses whose websites you have actually looked at, the mailbox you own is strictly better, and the pacing is the point rather than a limitation.
The follow-up sequence stops when someone answers
A three-touch sequence goes out on day 0, day 3 and day 7. Before each send the app checks your inbox for a reply from that prospect, and a reply stops the sequence immediately. Nobody gets a “just bumping this” after they already said yes.
Replies are read on-device and sorted — interested, not interested, out of office, wrong person, unsubscribe, and so on — so an auto-responder does not end a sequence that a human never saw, and a genuine no does end it.
The law wants your address in the email, so the app insists on it
US anti-spam law requires every commercial email to identify the sender and carry a real physical mailing address. Lead Scraper will not send at all until Settings → Outreach has your name and an address, and it puts them in the footer of everything it sends.
That is a deliberate block rather than a warning you can dismiss. It is your domain sending the mail, so it is your reputation and your liability — the app should not be able to spend either on your behalf while a required field is empty.
Try it on your own list
The free plan sends from your mailbox exactly like the paid ones — the metered part is scraping, not sending. Run a few scrapes, draft to a handful of real prospects, and watch where the replies land.
What is wrong with a shared sending pool?
Nothing, until someone else in it blasts a bought list. The pool's reputation drops and mail from people who did nothing wrong starts landing in spam — with no error, no bounce and no notification. Your open rate simply gets worse and you assume your copy went stale. The reputation you are borrowing was never yours to protect.
Does sending from your own mailbox improve deliverability?
It changes who controls it, which is the durable version of improving it. SPF and DKIM align to your own domain because it is your own domain, the reply-to matches the sender on a domain the prospect can look up, and nothing routes through a third party's tracking domain. Your sending reputation becomes yours to earn or to wreck, and nobody else can spend it.
How many cold emails a day can I send this way?
Fewer than a hosted sequencer, and that is the trade. Your own mailbox is not built to send ten thousand emails a day, and the app paces sends rather than emptying the queue at once. If your plan is high-volume blasting to a bought list, this is the wrong tool and a shared pool is genuinely what you want. If it is thirty well-aimed emails a week to businesses whose websites you have looked at, the mailbox you own is strictly better.
What happens when someone replies mid-sequence?
The sequence stops immediately. A three-touch sequence goes out on day 0, day 3 and day 7, and before each send the app checks your inbox for a reply from that prospect. Replies are also classified on-device — interested, not interested, out of office, wrong person, unsubscribe and so on — so an auto-responder does not end a sequence a human never saw, and a genuine no does end it.
Is cold emailing businesses legal?
In the US, commercial email is legal under CAN-SPAM provided it identifies the sender, carries a real physical mailing address, and honours opt-outs. Lead Scraper will not send at all until Settings → Outreach has your name and an address, and it puts both in the footer of everything it sends. Opt-outs are handled by a plain keyword pass that runs first and is authoritative — the on-device model can add an opt-out, never retract one. Other countries impose stricter rules; this is not legal advice.
