Senler report: the VK subscription funnel

VK mailing reports from Senler

Senler is a mailing service for VK communities. Businesses use it to collect subscribers into groups, run automated funnels and send messages straight to users’ inboxes. For targeting and SMM specialists, Senler is where advertising turns into a subscriber base. The client wants to know how many people subscribed, how many left and which sources work.

Reportkey connects to the Senler API and builds a section of a recurring report from those statistics, sent as a link or PDF on schedule next to ads and community statistics.

Connecting Senler: API key and community

Create the key in the Senler dashboard under Settings, API access. One key maps to one channel, meaning one community. A client with several communities needs a key for each, up to twenty in total. Enter the key with the community ID once on the Reportkey integrations page, then choose the community in a project. The key allows twenty requests per second, and Reportkey paces requests so a month of daily data is collected without errors.

Subscriptions, unsubscriptions and net growth

The main block is the subscription trend:

• subscriptions to the community’s mailings in the period;
• unsubscriptions in the same period;
• net growth, the difference, calculated by Reportkey.

Senler returns these as a single aggregate per requested period, so Reportkey requests each day separately for the daily chart and uses one request for weekly or monthly totals.

Subscriber groups

Senler gathers subscribers into groups for a lead magnet, webinar, course or promotion. The group block shows subscriptions and unsubscriptions for each. For an online school it reveals which free product attracts the audience best; for a store, which promotion pulled people in and where unsubscriptions followed.

Senler UTM tag statistics

The block targeting specialists value most shows subscription sources by tag. Senler lets you mark subscription links with its own tags and standard parameters such as utm_source and utm_campaign. The report shows subscriptions and unsubscriptions per tag, and with VK Ads spend next to it the client sees what a subscriber from each ad costs.

Broadcasts sent

The last block counts messages sent in the period, overall and per broadcast. The Senler API provides only the sent count, without opens or clicks, so site visits from broadcasts are better shown through UTM-tagged links in Yandex Metrica.

Reading Senler data

Senler subscriptions are mailing subscriptions, not community joins, so they need not match VK membership. Keys are tied to one community, which means an agency handling several communities for a client sets up a key for each.
