There's a lot of really really awesome things. I would say the team is just very open for us. Testing things out - different segments, different copy and they turn around time is just very, very quick which I really, really appreciate and that's been consistent since day one.

Sending a few emails here and there is easy -- sending at a consistently high volume and having them delivered every time is really really hard. Senders handles that for us in spades.

FAQ

Deliverability and Strategy

How is Senders different from other similar companies?

Unlike most other companies, we don’t use Google or Microsoft to send, which reduces the risk of reputation damage or your emails landing in spam.

Why should I use Apollo?

Apollo enables us to use Sendgrid and other proprietary tech tools for safe sending, without having to rely on Google’s infrastructure.

Who is Senders ICP?

We work with small to medium-sized B2B companies across various industries (many of our clients are SaaS), mainly in the US, Canada, and the EU.

What is your pricing structure?

Our pricing varies depending on each client’s needs, but our deliverability service starts at $1200. You can learn more about our pricing here.

Which platform do you use to send out the emails?

We manage the infrastructure without owning the sending platform. Instead, we connect with platforms like SendGrid.

How long does it take to reach the full volume of sending?

With our warming protocols to protect deliverability, it takes 7 weeks or more depending on the time of year – holidays may extend the process.

Are the replies automatically encoded?

No, your Strategist/Account Manager does that manually.

What does warm-up mean?

Among other things, warming entails gradually increasing the volume of emails sent from a new email domain/subdomain to build a positive sending reputation with Internet Service Providers (ISPs).

If we’re paying for three senders why do we only get Strategy services on one?

We have defined the Strategy service in a way to provide maximum value for each client despite the number of senders you may have. While the Strategist will dedicate their expertise to one sender, you can always leverage that knowledge to optimize performance for the other senders, as well.

How can you ensure that someone who has already replied isn't emailed again?

Apollo automatically disqualifies (removes) anyone that either replied, bounced or unsubscribed from the email sequence.

How do you handle email testing?

We always provide at least two email variants for the most important steps in your sequence (such as step one and step three), so that we can track their performance and spot best-performing email variants for different target groups. We also test out different subject lines and react quickly if we notice any drops in performance, so we can adjust the copy while campaigns are running.

What are “email sequences”?

An email sequence is a series of emails (at least two, usually no more than five) that we send out to a specific target group, several days apart, depending on our agreement with you. We call the first email “the first step” of the sequence, while the second email is called “a nudge” and is usually a short follow-up we send a couple of days after the first. The number of steps (emails) in a sequence depends on your industry, target audience, and your goal, so we adapt the approach specifically to your business and outreach goals.

Can we ramp-up faster?

We have done extensive experiments, and over time, we have seen that the best, safest way forward is slowly and gradually ramping up by increasing the sending volume by 25 emails per day. We do not recommend ramping up faster, as it may affect your reputation and overall deliverability.

Why do we need to set up email filters on our receiving end?

Usually, forwarded emails tend to “break” the technical backend such as SPF, DKIM (your email authentication methods) and that can send emails to spam. To prevent that, we make sure that any email that is forwarded from our system to your mailbox will end in your inbox – this is where setting up those filters correctly makes all the difference.

Copywriting

What will you base your email copy on for my campaigns?

We have a discovery form you can fill out to give us specific information that you’d like us to include in the strategy and the copy. That also includes your targeting goals, as well as examples of emails you like or have had success with in the past. We combine that information with our own internal best practices based on the thousands of emails we’ve written and sent over the years. On top of that, we pick out the best-performing approaches for your industry, customize them to your needs, and test them out for you, as well.

What if I don’t like the email copy you provide?

We always go through as many rounds of edits and changes as we need to create the kind of emails you will be happy with. However, we also track your campaigns’ performance to jump in and adapt the copy over time so that we can maximize your results.

Do you send the same emails to all target audiences?

We don’t. To maximize deliverability and to make sure each target group receives the kind of message they will be most likely to respond to, we tailor the emails to each of your target groups. Sometimes, there will be some overlaps in the core message and your value proposition, but we will vary the language for better deliverability.

Can we include links in the email copy?

In some emails and some steps, we can include links to your website and to specific pages you want people to visit (such as sign-up pages). However, we strive to create a balance between emails with and without links to see which ones perform better for your specific target audience. And of course, we always want to include unsubscribe/opt-out links in emails.

How important is email copy for deliverability?

Email copy is an important part of ensuring high deliverability for your campaigns, but it is definitely not the only segment we’re taking care of and tracking. The better the copy is and the better your product-market fit, the greater the engagement will be, so we do our best to create engaging copy that will improve open rates, click-through rates, and replies.

Do you use AI for copywriting?

No, we don’t use AI for writing our emails. We have a team of exceptional strategists and writers that work together with you to create the kind of copy you will be happy with, aligned with our best practices and years of experience.

Is copywriting included in all your deliverability services?

Email copywriting is considered an add-on. While it is included in the strategy service, it is not part of our deliverability-only service tier called Protocol. If you need help with copywriting, however, but you don’t want the full strategy service, we can provide a dedicated copywriter for as many sessions as you need, either to write the copy for you from scratch, or to review/adjust your existing copy to make it deliverability-friendly. You can learn more about all the available add-ons on our Pricing page.

Partnerships

Do you whitelabel?

We typically don’t do whitelabel partnerships, unless it is the only solution that makes sense for everyone involved.

How can I be part of your Partnership community?

You can reach out to us via our Partnerships page to express interest and meet our Partnership Manager, Aurora. During that call, you can share your goals, get a better idea of the criteria for joining and learn more about the program itself. If there’s a fit, you can proceed with the application. We also like our partners to stay engaged for ongoing collaboration, to make sure everyone can benefit from the relationship.
