Where the category beats us
3 rows, stated plainly. If this is what you need, buy the other thing. You will be happier and we would rather you did.
Where do the contacts come from. The category is stronger here.
- MastroSDR
- Search a trade and a place. Business search finds the companies, then MastroSDR reads each one's own website and takes the address it publishes there. Nothing is invented. You can also paste or upload a list you bought elsewhere. A business publishing no address arrives without one.
- The category
- A licensed contact database, often hundreds of millions of records, with verified direct dials and job titles. That is genuinely more than we have, and if you need direct dials you need one of them.
Does it plug into my CRM. The category is stronger here.
- MastroSDR
- One way, out. Every reply, booking, bounce and unsubscribe that reaches us is posted to any endpoint you add, signed so you can prove it came from us. There is no two-way sync: nothing is ever read back out of your CRM. Zapier, Make, n8n and a handler you write yourself all read that webhook, which is how it reaches whichever CRM you use.
- The category
- Two-way sync with the major CRMs is standard, and reading back is genuinely theirs. If your team lives inside a CRM and needs changes to flow both ways, that is a real reason to choose them.
Does it book the meeting. The category is stronger here.
- MastroSDR
- Not here, and this is the one row where they beat us. Booking needs one mailbox that can both read the reply and write to your calendar, and no mailbox you can connect on this deployment does both. A reply asking for a time still reaches you in Replies, with the words drafted, and you put it in your own calendar.
- The category
- Most of them book too, and the funded ones do it well. MeetChase charges $50 to $60 per meeting booked.
What the $49 actually buys
- 5,000 new companies found a month, read from their own websites
- 2,000 emails written for you, with no key to connect first
- Sends from a mailbox you own and signed into yourself, with no cap you will reach
- Prospects held and mailboxes connected without a cap you will reach
- One inbox across every mailbox, and a reply that comes back to MastroSDR stops that person's follow-ups
- Sending set up on your domain: the DNS records published, replies routed back to a catch-all that needs no confirmation, and a ramp from 10 a day that no setting raises. A domain bought here is $25 a year on any plan.
The only thing metered in practice on a paid plan is how many new companies get found each month. Sending costs us nothing, because it leaves through your mailbox rather than ours, so there is no reason to charge you for it.
Choose MastroSDR if
You are selling your own service and you want to read what goes out. You would rather pay $49 with nothing metered but the search than $500 and a credit balance.
Choose one of them if
You have a sales team, you live in a CRM, and you want LinkedIn sent for you rather than handed to you. A licensed database with direct dials is real, and we do not have one.
No card. 500 new companies found a month and 500 sends, so you find out whether it works before paying anything.
Prices are list prices and move. If you find one of these out of date, tell us and it gets corrected.
