# Guides on B2B cold email, outbound, and automation > Plain guides on done-for-you cold email, outbound sales systems, hiring an SDR, domain risk, cost, and what a booked sales call is worth. Canonical: https://syncsolved.com/research Last updated: 2026-10-24 Each guide answers one question a B2B buyer asks before paying for outbound help. SyncSolved is a B2B automation company that builds and runs outbound sales systems, so these guides explain how that work is done and what it costs. ## What do these guides cover? The guides cover five topics. First, whether to run cold email yourself, hire an in-house SDR, or let a done-for-you team run it. Second, how to keep your main company domain safe by sending from separate domains. Third, why a reply is not the same as a booked call, and what happens between the two. Fourth, how to choose an outbound service and what to ask before you sign. Fifth, how to work out what a booked sales call is worth to your business. ## How should you use them? Start with the question closest to your problem. If you are not sure whether outbound is worth it, read what a booked call is worth and use the cost of outbound calculator. If you already send cold email and it has stalled, read how to revive stalled outbound. If you are comparing providers, read how to choose a cold email service. The calculator numbers are planning guesses from the numbers you type. They are not client results. Each guide shows the date it was last updated. Prices are stated as of October 2026. ## All guides - [Doing it yourself vs letting us run it](https://syncsolved.com/research/diy-vs-dfy-outbound) - Updated 2026-10-23.
