At a glance

Sellsius in detail

Sellsius recruits, employs and manages South African sales and customer service teams. That makes it the stronger starting point when your buying brief is about people: which roles to fill, what work those people should own and how the team will operate.

Before requesting a proposal, write a role brief. Include the responsibilities, target customers, working hours, reporting structure and skills you need. Separate sales work from customer service work so that you can assess candidates and service scope against a clear requirement. A broad request to improve sales leaves too much room for different interpretations.

Ask Sellsius to explain which responsibilities sit with your business and which sit with its team. Request written terms covering recruitment, employment, management and the end of the engagement. Compare those terms with the work your current managers can realistically supervise. Our in-house SDR versus cold email agency guide offers another way to frame that staffing decision.

Modern Inbound in detail

Modern Inbound sells done-for-you outbound through cold email for B2B teams, billed quarterly. It runs the copy and targeting, making the service hands-off for the client. It tests 50 to 100 messaging angles a month.

Mailboxes and domains are bought in the client's name, and the first 14 days are a free warm-up. Include infrastructure ownership and preparation time in your buying checklist. Those details affect what you need ready before outreach begins and what access your business should retain.

A warm lead is a reply from a real potential buyer, or a route to one, that shows interest and has a clear next step. Each warm lead is handed over as an introduction. Decide who on your team will take those introductions forward before starting. The handover is only useful when someone has responsibility for the next step.

Modern Inbound's published proof is 6,000+ warm leads. Use that alongside an assessment of service scope, target market and your own capacity to follow through. For a practical preparation checklist, read what to expect during cold email agency onboarding.

Who should choose which

Choose Sellsius when the missing piece is a team

Choose Sellsius when your brief calls for South African sales or customer service people and you want a provider to recruit, employ and manage them. Start with the role and the work it must cover. Ask how performance will be assessed, how feedback reaches the team and what happens when your requirements change.

Choose Modern Inbound when the missing piece is outreach execution

Choose Modern Inbound when you want cold email copy and targeting run for you. This fits a buying brief focused on outsourcing outreach while your team takes warm-lead introductions forward. Define your target customers and the next step you want an interested buyer to take. Our guide to evaluating a lead generation agency can help structure the comparison.

Can you use both?

You can consider both when your plan contains separate needs for outreach and team capacity. Write down who owns prospecting, who receives an introduction and who moves the opportunity forward. Choose the first engagement around your immediate gap, then assess whether a second provider adds a distinct responsibility worth paying for.
