Increasing outbound contact rates

Contact rate is the percentage of leads that you’re able to reach. You can track yours on the Analytics page. Two things work against it: carrier spam filters that block or flag your calls before they ring, and whether the lead chooses to answer the call when it comes in.

PeakSend works to both decrease spam flags on your outbound calls, and increase the likelihood of leads answering. The system manages your number inventory to avoid spam mislabeling and times your calls to reach people at different parts of their day. When local presence dialing is enabled, it also uses local numbers to increase the odds they pick up.

Number inventory management

Your number inventory (sometimes referred to as DIDs) is the pool of outbound phone numbers PeakSend uses when your agent dials a contact. Rather than calling from a single number, PeakSend rotates across the pool to distribute volume evenly. A short cooldown window between uses on the same number adds further spacing. When call volume grows beyond what your current pool can handle, PeakSend provisions new numbers automatically.

This matters because carrier analytics flag numbers that show sudden volume spikes or inconsistent patterns. By spreading calls across multiple numbers and ordering them by least recently used, each number maintains a consistent, moderate call volume.

Pre-purchase spam screening

Phone numbers get recycled. A number you acquire today may have been used by a previous owner in ways that left it flagged as spam. Calling from a number that already has a negative reputation just moves the problem around.

Before adding any number to your inventory, PeakSend checks it against reputation databases. Numbers with existing spam flags, fraud history, or other red marks are rejected, so only numbers with a clean reputation enter your pool.

Automatic warmup

Carrier analytics track per-number baselines. A brand-new number that suddenly makes hundreds of calls in a day looks suspicious because it has no history and no established pattern.

PeakSend starts new numbers at a low daily call volume and increases it gradually based on actual usage. As the number builds a track record of normal calling behavior, its daily limit rises. This way, each number establishes a reputation with carrier systems over time instead of showing up at full volume with no history.

STIR/SHAKEN attestation and registration

STIR/SHAKEN is an FCC-mandated framework for cryptographic caller ID authentication, established under the TRACED Act. When a call is placed, the originating carrier signs it with a cryptographic token that verifies the caller is authorized to use that number. The receiving carrier checks the signature and assigns an attestation level:

• Full attestation (A): the carrier knows the caller’s identity and confirms they are authorized to use the number
• Partial attestation (B): the caller is verified, but authorization for the specific number is unconfirmed
• Gateway attestation (C): the call entered the network from a gateway and neither the caller nor the number can be fully verified

Calls with full attestation are less likely to be flagged as spam. PeakSend registers all numbers in your inventory for full attestation and enrolls them in carrier spam remediation programs. This tells carrier analytics systems that your numbers belong to a verified business, which reduces the odds of being marked as spam. For more on outbound calling regulations, see TCPA compliance.

Answer rate monitoring

Even with rotation, warmup, and authentication in place, individual numbers can still get flagged. Spam labeling systems are opaque, and a single batch of user complaints can tank a number’s reputation.

PeakSend tracks answer rates per number and compares them against the expected baseline for the agents using that number. If a number’s answer rate drops below what it should be (suggesting it has been flagged), the system pulls it from rotation and puts it on cooldown. The number stays out of the pool until it has had time to recover.

Call delivery

Even when a call isn’t flagged as “spam likely”, leads might not answer the phone. PeakSend increases answer rates using optimized follow-up cadences and local presence dialing.

Optimized cadences

Not everyone picks up at the same time of day. Some people answer morning calls, others are only reachable in the evening. If you always call at the same time, you’ll keep missing the same people.

PeakSend rotates follow-up attempts through morning, afternoon, and evening windows in the contact’s timezone, so each attempt hits a different part of their day. Combined with spacing attempts out over days and weeks, this increases the odds of catching someone when they’re actually available. For details on how the cadence works, see Automatic follow-up cadences.

Local presence dialing

People are more likely to answer a call from local numbers. A recipient in Atlanta seeing a 404 area code on their screen is more likely to pick up than if the call comes from an unfamiliar region.

Local presence is a paid addon with two tiers:

• Basic: matches the recipient’s state. Your agent calls from a number in the same state as the contact.
• Advanced: matches the recipient’s area code. Your agent calls from a number with the same area code as the contact.

Local presence works together with number rotation. When your agent dials a contact, PeakSend selects a pool number that matches the contact’s geography, using the same rotation and warmup rules described above.
