Send Responsly survey invitations through SendGrid for high-volume deliverability and domain consistency
SendGrid is the email delivery infrastructure behind a substantial share of transactional and marketing email at scale. Responsly plugs into SendGrid so your survey invitations inherit the same deliverability, domain reputation, and template library you already use for everything else.
For enterprise teams, high-volume survey programs, and organizations with established SendGrid investments, this integration is how survey emails land in inbox instead of spam — at any volume, from your own trusted domain.
Where SendGrid and Responsly work well together
High-volume survey invitations
Monthly NPS sends to 100K customers, quarterly engagement surveys to employees, or post-purchase surveys triggered at checkout — all benefit from SendGrid’s delivery infrastructure. Dedicated IP, warmed domain, and established sender score keep landing rates high.
Transactional post-event surveys
A survey triggered by an app event (purchase, signup, booking) sends through the same SendGrid infrastructure as the confirmation email. Brand consistency stays intact; deliverability is uniform; respondents recognize the sender immediately.
Branded reminder sequences
Survey reminders at day 3 and day 7 to non-respondents typically double total completion rate. SendGrid handles the suppression logic (already-respondents skip), template rendering, and timing. Response rates rise without additional infrastructure work.
Multi-language survey campaigns
Global survey programs need localized invitation emails. SendGrid’s dynamic templates plus Responsly’s multi-language survey support give a clean one-template-per-language setup that scales to 20+ languages without custom engineering.
Deliverability analytics
Low response rates on a survey might be a content problem or a deliverability problem. SendGrid’s analytics surface the distinction: if open rates are fine but response rates are low, the survey needs work; if open rates are low, deliverability is the issue.
Setting up Responsly with SendGrid
- Generate survey invitation links in Responsly. Unique per-recipient URLs with hidden fields for identification.
- Design the SendGrid template. Dynamic template with recipient-specific survey link as a variable.
- Build the send automation. An automation layer pulls the Responsly recipient list, pushes to SendGrid’s API with personalization data.
- Configure SendGrid suppression. Ensure survey sends respect the global unsubscribe and suppression lists.
- Monitor deliverability. SendGrid’s dashboard surfaces bounce rates, open rates, and spam complaints per send.
Practices for healthy survey deliverability
Warm the domain before scale. New sender domains need gradual volume ramp. Start with smaller segments before hitting the full list.
Segment send times by timezone. A 9 AM send in the recipient’s local time dramatically beats a single-time blast. SendGrid supports timezone-aware scheduling.
Keep subject lines honest. Clickbait subject lines damage sender reputation fast. “Quick feedback on your recent order” outperforms “You won’t believe what we’re offering!”
Respect frequency caps. Even a well-regarded sender gets flagged if the same recipient receives survey invitations weekly. One per 30 days is a safer cadence for most programs.
Split-test invitation copy. A/B test subject lines and body copy on a small segment before full send. 10-15% response rate lifts from copy optimization are common.
Survey emails that actually reach the inbox
Connect Responsly to SendGrid and survey invitations stop competing with marketing mail for deliverability. Your existing domain reputation, templates, and analytics carry through — so survey programs scale reliably without re-engineering the email layer.
